* perf: eliminate dual-connection DB pool contention across worker, queue, and api Reuse the held transaction (or move pool reads before begin()) instead of checking out a second pool connection while a tx is open, extending the fix from #9789/#7861. Targets the per-worker pool (max 5) hot paths plus several server-pool API handlers.

The caller swallows the error and keeps using tx, so a DB read failure must not leave the outer transaction aborted (it would fail the later commit). Matches the previous pool-read semantics. - Revert reads that were moved onto an RLS (user_db) transaction back to the non-RLS pool, since RLS row-visibility/role context can change results: push_scheduled_job (email/tag/settings lookups; reachable with a user_db tx from api-schedule/api-flows), push_inner native-retry dedicated_worker routing (RLS isolation variants), resources.rs app-namespace folder auto-create (non-admins must not be blocked), and the script archive/delete UPDATEs. Non-RLS db.begin() reuse and move-before-begin are kept.

The test asserts the flow still completes (iteration marked failed) — which only holds if the savepoint keeps the outer status-update transaction committable. Without the savepoint the abort would poison the outer tx and the job would never complete.
