Maurice 4fa2f3dc8b feat(db): give every dialect helper a Postgres branch ...

The dialect layer promised that a second engine would be a branch in
src/db/dialect/ and no sweep through the repositories, but every helper
only knew SQLite and threw for anything else. Each one now has a Postgres
branch, and the helpers whose text both engines read alike (COALESCE,
LOWER, TRIM, substr, ||, the aggregates, the CASE shapes) share one
spelling behind isKnownPlatform.

The Postgres branches keep the storage model SQLite has: the clock helpers
render UTC as the same YYYY-MM-DD HH:MM:SS text (to_char over CURRENT_TIMESTAMP
AT TIME ZONE 'UTC'), GLOB becomes an anchored regular expression, the integer
cast truncates through numeric so '14.0' still reads as 14, JULIANDAY
distance comes from the epoch difference, SQLite's null-safe IS becomes IS
NOT DISTINCT FROM, and NOCASE names a nondeterministic ICU collation a
Postgres schema creates. Bound values on the Kysely side are cast to text
where pg would otherwise send an untyped parameter the planner cannot
resolve.

The SQLite branches are untouched, so nothing changes for a running
install. The Postgres text is pinned in sql-functions.postgres.test.ts.
