TEST: Session management and history recording tests

[mondominator]

Priority: HIGH

Tests Needed

Unit Tests (services/monitor.test.js):

• shouldAddToHistory() function with all filter combinations:
  • User with history_enabled = 0 → false
  • Stream duration < 30s → false
  • Progress < 10% on non-audio → false
  • Exclusion pattern match → false
  • All criteria met → true
  • Audiobooks ignore progress filter
  • Custom settings override defaults

Integration Tests (session-lifecycle.test.js):

• New session creation
• Session update (same media) - progress only
• Session update (media change) - stops old, creates new
• Session state transitions (playing → paused → stopped)
• Session resume after stop (new session created)
• Stream duration calculation
• History entry creation with all required fields
• Duplicate prevention (one history per session)
• User stats updated (total_plays, total_duration)

Acceptance Criteria

• Session lifecycle fully tested
• History filtering logic verified
• Edge cases (paused timeout, stale cleanup) covered
