perf(critical): Implement P0 optimization fixes - TiviMate parity
CRITICAL FIXES:
- P0-1: Fix EPG N+1 query storm with batch loading
* Implement XtreamServiceMobile with getBatchEPG() method
* Batch load EPG data instead of per-channel requests
* Reduce 50-200 concurrent requests to 1 request per category
* Add EPG cache with 1-hour TTL to prevent redundant calls
- P0-2: Remove destructive cache clearing on startup
* Implement TTL-based cache invalidation
* Preserve cache between app launches (6h channels, 1h EPG, 30m search)
* Add HiveService.invalidateExpiredCache() method
* Expected: -80% startup time on cold launches
- P0-3: Preserve tab state with IndexedStack
* Replace switch statement with IndexedStack
* Keep all tabs alive in widget tree
* Preserve scroll position, search state, filters across tab switches
* Expected: instant tab switching (<100ms)
HIGH PRIORITY FIXES:
- P1-1: Debounce search input (500ms)
* Prevent per-keystroke full rebuilds
* Add search debounce timer
- P1-3: Fix double FocusNode disposal crash
* Remove duplicate focus node disposal in native_player_screen.dart
* Prevents StateError on player exit
Expected impact: -75-80% perceived latency, instant tab switching, no OOM on startup.
