Problem

Loading the row count for a table whose filter contains a quoted string value
failed with ERROR: unterminated quoted string, so the count stayed stuck on
the # button. Filters with only numeric comparisons worked fine.

Root cause

macOS "Smart Quotes" rewrites a typed ' into a curly ‘/’ (U+2018/U+2019)
in the toolbar's WHERE/ORDER BY inputs. SQL only treats a straight ' as a
string delimiter, so a clause like col = 'value' reached the database as
col = ‘value’: the curly char is an ordinary character and the leftover
straight quote opened a string that never closed. The count query —
SELECT COUNT(*) FROM (…) as count_wrapper — then failed to parse. The grid
query ran before macOS finalized the conversion, which is why only the count
broke.

Fix

Fold typographic quotes back to straight ASCII inside reconstructTableQuery —
the single builder every table query (grid and count) flows through — so the
SQL that reaches the database is always valid, regardless of what's stored. This
also fixes it for a filter that was already stored with a curly quote, without
needing to re-apply it.

Testing

• Added a reconstructTableQuery test: a curly-quote filter reconstructs to
  straight quotes.
• tsc --noEmit clean; editor util tests pass.
