feat(rollups): v1.4.35.1 — auto-converge rollups on worker boot

Removes the operator step that was implicit in the v1.4.35 foundation.
Self-hosters no longer need to run the backfill script after upgrade.

New `rollup-full-backfill` queue + handler folds one user per job at
serial concurrency. `enqueueBootTimeRollupBackfill` runs once at
`startReminderWorker` boot, discovers accounts with measurements but
zero rollup coverage, and enqueues one full-fold job per uncovered
user with a singleton key so fast restarts don't pile up duplicates.

Best-effort: discovery errors surface through the helper's return
value and are logged via workerLog; the worker boot never fails
because the backfill missed.

Tests: 4280 → 4285 unit + 228 → 230 integration. tsc + lint clean.
