Subject: [PATCH 1/2] feat: resilient background job retry & monitoring (#130)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds production-grade retry logic and execution monitoring for all
background jobs, resolving issue #130.

New service (app/services/job_retry.py):
- JobRecord     — per-job dataclass tracking run_count, success_count,
                  failure_count, last_run, last_success, last_failure,
                  last_error, status (idle/running/success/failed)
- JobMonitor    — thread-safe in-process singleton registry
- retryable()   — decorator factory: wraps job fn with exponential-backoff
                  retry (configurable max_retries, backoff_base) and auto
                  records every execution in the JobMonitor
- _dispatch_due_reminders_job(app) — sends all due unsent Reminder rows
- init_job_scheduler(app) — registers reminder_dispatch on APScheduler
  (every 1 min) wrapped with retryable(); stores scheduler at
  app.extensions['job_scheduler']

New routes (app/routes/jobs.py):
- GET  /jobs/status           — JWT required; returns all job records
- POST /jobs/trigger/<job_id> — JWT required; manually fires a job

app/__init__.py:
- Calls init_job_scheduler(app) on startup (skipped when TESTING=true
  or DISABLE_SCHEDULER is set)

Tests (tests/test_job_retry.py — 20 tests):
- JobMonitor: register/idempotent/all_records/to_dict
- retryable: success, retry-on-failure, recover-on-2nd-attempt,
  permanent-failure, error-cleared-on-success, timestamps, run_count
- HTTP: GET /jobs/status auth gate, JSON shape, registered job visible,
  record key structure
- HTTP: POST /jobs/trigger auth gate, 503 when no scheduler
- Dispatch job: runs without error in fresh DB context
