tests: Add smoke tests for scheduled jobs system (auto-send & ops scheduling)

Add 30 fast static verification tests (<0.1s) covering:
- Auto-send user persistence (DB, handlers, template, task integration)
- Auto-send delay validation (1-60 minute range, clamping, defaults)
- Convert Library & EPUB Fixer scheduling (routes, endpoints, DB, UI)

Tests verify code structure exists without requiring Flask dependencies,
ensuring proper integration before runtime execution.

All tests passing (30/30) in 0.06s
