## What this PR does

Harbor's app chart renders a nested HelmRelease that owns the whole
workload: the Deployments, the inline RedisFailover and its volume. It
had no install strategy, so it got Flux's default, and install
remediation is an uninstall in every case Flux offers. A first install
that misses its budget gets torn down, and the next one provisions the
redis volume and runs the master election again from scratch.

That happens on a loaded runner. harbor-core waits on redis, redis waits
on its volume and the master election, and the nginx Deployment hits the
default `progressDeadlineSeconds` of 600s. Flux reads that as a stalled
resource and fails the install early. The e2e wait budget is 10m, the
same as the deadline, so after a teardown the second attempt has less
time than a first install needs.

`RetryOnFailure` keeps the manifests applied and retries as an upgrade.
Nothing is deleted, so the volume, the elected master and harbor-core's
startup all survive, and the retry costs 30s instead of a full install.
A Deployment clears `ProgressDeadlineExceeded` by itself once its pods
go ready, so the retry lands as soon as the stack converges.

This drops the teardown, not the deadline. The suite applies the release
in one step and waits for it in later ones, so part of the budget is
still left when the fail-early hits. That leftover is useless to a fresh
install and usable to a retry that resumes. Whether the deadline or the
budget also needs moving is a separate question, and an early deadline
only becomes safe once a failed install stops being torn down. In
production the win holds without any of that: a slow first install no
longer deletes the Redis volume and the database.

Both actions carry the strategy. The controller runs the retry of a
failed install as an upgrade, so with install alone the retry's own
failure falls through to upgrade remediation. The remediation blocks
stay: an absent release consults install, an out-of-sync one consults
upgrade, both by retry count rather than by strategy.

It goes on the nested release, not the parent. The parent is built from
the Application by the apiserver, which already stamps this strategy on
both actions. The nested one owns the workload and the volume a
remediation deletes.

Same shape as the tenant CNI and CSI releases in #3552 and #3581, and
the unit test follows theirs. Relates to #3445.

## What this PR does

The tenant chart renders the etcd and seaweedfs releases with no install
strategy, so they get Flux's default, and install remediation is an
uninstall in every case Flux offers. Neither release sets
`spec.uninstall.disableHooks`, which defaults to false, so that
uninstall runs the app chart's `post-delete` cleanup Job. Nothing
unusual is configured anywhere along that chain: fail early, uninstall,
hooks.

Those Jobs delete data on purpose. The etcd one removes the
`data-etcd-<ordinal>` PVCs by name, because the etcd-operator does not
reclaim them when the EtcdCluster goes. The seaweedfs one removes the
volume PVCs by label and explicitly reclaims the keep-protected CNPG
Cluster holding the filer metadata, because nothing else would. Both are
right for a real uninstall, and neither hook is at fault here.
Remediation is what calls them, on a release that is only starting
slowly.

So an install that misses its budget does not restart. It destroys the
datastore the tenant control planes keep their state in, or the object
store's data together with the metadata database that indexes it, and
the next attempt begins from nothing.

That budget is not a comfortable margin. The seaweedfs release has
`timeout: 10m`, and `hack/e2e-install-cozystack.bats` already records
that on a loaded runner the tenant stack only starts creating pods
around 9 to 10 minutes in. The window CI observes and the window that
triggers this are the same window.

`RetryOnFailure` keeps the manifests applied and retries the failed
release as an upgrade. No uninstall happens, so neither cleanup Job runs
and the install already under way carries on instead of starting over.

Both actions carry the strategy. The controller runs the retry of a
failed install as an upgrade, so with install alone the retry's own
failure falls through to upgrade remediation. The remediation blocks
stay: an absent release consults install, an out-of-sync one consults
upgrade, both by retry count rather than by strategy.

One trade is that a real upgrade failure retries instead of rolling
back. That costs no stable safety net. With `retries: -1` and the
default strategy, upgrade remediation was already rolling back and
retrying without end, so the release never rested in the rolled-back
state either.

The other side of the trade is that the uninstall was also the only
automatic clean slate. On a tenant holding no data yet, an install that
wedges on a bad resource state now retries against that state until an
operator removes the release. For a release that owns data that is the
right exchange, because lost data does not come back and a wedged
install does.

This covers two of the tenant's data-owning releases. The monitoring
release carries the same default and a cleanup Job that deletes its PVCs
as well, and is left for its own change, as is the rest of the catalog,
whose nested releases want the question asked one at a time. Same shape
as #3552 and #3581. Relates to #3555 and #3576.

## What this PR does

The tenant chart renders monitoring and gateway with no install
strategy, so they get Flux's default, and install remediation is an
uninstall in every case Flux offers. Neither sets
`spec.uninstall.disableHooks`, which defaults to false. So a release
that missed nothing but a readiness budget gets uninstalled, and the app
chart's `post-delete` cleanup Job runs against it.

Those Jobs delete on purpose, and they are right to. The monitoring one
removes PVCs labelled
`apps.cozystack.io/application.name=<release>-system`. That label is not
incidental either: the metrics and logs claim templates stamp it so the
operator copies it onto the storage PVCs, and the Job selects on it to
stay release-scoped. Both ends were built to meet. The result is that a
slow first install deletes the tenant's metrics and logs, and nothing
reconstructs them.

The gateway Job deletes the `cozystack-acme-account` Secret. That key
regenerates, so this one costs no data. It costs a re-registration
against the ACME provider, and repeated cycles run into its rate limits,
which can hold certificate issuance for the tenant down for hours.
Smaller stake, same mechanism, and the two are not one class: only one
of them owns storage.

`RetryOnFailure` keeps the manifests applied and retries the failed
release, so no uninstall happens and neither Job runs. Both actions
carry the strategy because the controller performs that retry as an
upgrade, so with install alone the retry's own failure falls through to
upgrade remediation. The remediation blocks stay: an absent release
consults install, an out-of-sync one consults upgrade, both by retry
count rather than by strategy.

Two things are traded away. A real upgrade failure now retries instead
of rolling back, which gives up no stable safety net, since with
`retries: -1` the default strategy was already rolling back and
re-upgrading without end. And the uninstall was the only automatic clean
slate, so an install wedged on a bad resource state retries against that
state until an operator removes the release. For a release that owns
data that is the right exchange.

This removes the consequence rather than the trigger, and for monitoring
the trigger is worth naming separately: the parent HelmRelease here
waits `10m`, while the child `monitoring-system` release sets `15m`
deliberately, with a comment explaining that 10m is too short for the
OIDC users-Job inside its `activeDeadlineSeconds: 900`. The parent's
wait covers the child, so the parent can fail while the child is
behaving exactly as designed. That mismatch is untouched here and wants
its own change.

The chart's etcd and seaweedfs releases lose storage the same way and
are outside this change. Beyond those four, computeplane, ingress and
info stay on the default strategy, but their charts ship no destructive
`post-delete` hook, so remediation costs them a wasteful teardown rather
than data.

Same shape as #3552 and #3581. Relates to #3624.
