Replace direct *pgxpool.Pool usage with PoolProxy wrapper across the entire backend:
- db.DB renamed to db.Conn (*pgxpool.Pool -> *PoolProxy)
- JWT functions now accept context.Context instead of using context.Background()
- Handler DB calls route through PoolProxy for per-test transaction support
- Fixture/helper/testdb functions accept Querier interface for decoupling
- Query ordering fixed in bookings handlers: COUNT after data query to avoid pgx conn busy
- Time truncation fixed: time.Date instead of Truncate(24*time.Hour) for week start calc
- testmain_test.go files updated with SeedBaseline and NewPoolProxy

DeleteAccountHandler now scrubs external systems BEFORE SQL-level anonymization. S3: deletes profile picture from S3/R2 (profiles/{userID}.jpg) when s3.Client is configured. Square: iterates user's saved cards and calls DeleteCardOnFile for each non-deleted card when payments.SquareClient is configured. Both run in background goroutines (non-blocking, best-effort with warning logs). CardDAV contact deletion remains as existing best-effort goroutine.
