P1: every repo, route, scheduler path and test now speaks one async DB
interface (all/get/run/exec/transaction). better-sqlite3 stays underneath
for dev/tests via SqliteDb (statement cache, manual BEGIN/SAVEPOINT
nesting); openDb stays sync so fixtures remain one-liners. Zero behavior
change: 346/346 tests, typecheck clean.
P2: migrations-pg.ts — numbered Postgres migration set (001-init: bigint
paise, integer flags, TEXT ISO dates, TEXT JSON; reminder CHECK born in
final widened form) + schema_migrations runner.
P3: db-pg.ts — pg Pool behind the same interface: ?->$n rewrite outside
string literals, transactions pinned to one pooled client via
AsyncLocalStorage with savepoint nesting, int8/numeric parsed to JS
numbers so paise math is identical on both engines.
Also: reminder upsert INSERT OR IGNORE -> ON CONFLICT DO NOTHING
(portable, same changes-count semantics).

Serve the document PDF as an attachment with a doc-no-derived filename
("QT/26-27-0001" -> "QT-26-27-0001.pdf", null docNo -> "draft.pdf") when
?download=1 is present; keep the default inline so the composer iframe
preview still works. renderPdf is now injectable into apiRouter so the
header logic is tested without launching Chrome (house DI pattern).
