sassanix 60239bd637 Fix Apprise notification system, scheduler stability, and email configuration
Fixes & Enhancements

* Resolved five critical Apprise notification issues:
  • Ensured configuration reload during scheduled jobs
  • Fixed warranty data fetching for Apprise-only users
  • Refactored notification dispatch logic with dedicated helpers
  • Corrected handler scoping via Flask app context
  • Wrapped scheduler jobs with Flask app context to prevent context errors
  → Verified: Scheduled Apprise notifications now work reliably for "Apprise only" and "Both" channels.

* Added support for SMTP\_FROM\_ADDRESS environment variable, allowing sender address customization independent of SMTP username. (PR #115)

* Fixed duplicate scheduled notifications in multi-worker environments:
  • Strengthened should\_run\_scheduler() logic
  • Now guarantees exactly one scheduler instance across all Gunicorn modes.

* Fixed stale database connection handling in scheduled jobs:
  • Fresh connection acquired each run, properly released via try/finally
  • Eliminates "server closed the connection" errors.

* Definitive scheduler logic fix for all memory modes (ultra-light, optimized, performance):
  • Single-worker runs scheduler if GUNICORN\_WORKER\_ID is unset
  • Multi-worker: only worker 0 runs scheduler.

Impact

* Apprise and Email notifications are now stable, reliable, and production-ready
* No more duplicate or missed notifications across all memory modes
* Improved system efficiency and robustness
