Marc-André Bombeck d640eea32a test(integration): hold statement budgets on the hot routes ...

tests/integration/query-counter.ts counts the statements the app sends
while a function runs, by wrapping Client.prototype.query on the copy of pg
the Prisma adapter itself resolves (so a second pg in node_modules cannot
leave it reading zero; a window with no statement throws). Background tasks
are settled before the window closes, so fire-and-forget writes count with
the request that started them.

query-budget-hot-routes.test.ts seeds a small account (four months of the
main types with overlapping sources, stats rows, sleep, glucose, a
medication, workouts and mood), warms each route once, evicts the user's
caches and counts the next call. Budgets, measured on this fixture:
/api/auth/me 18, dashboard summary 86, dashboard snapshot 103, pulse series
30/365/3650 days 6 each, day view 48, insights health status 60,
correlations 44, a 500-row batch ingest 31. A failure prints every
statement grouped by text.

Proof: one extra `SELECT 1` before every handler in apiHandler failed all
ten budgets by exactly one (18 → 19, 86 → 87, … 31 → 32), which also shows
the counts are deterministic; with the probe removed all ten pass.
