Fix Debrid-Link key rotation cascade failure, case-sensitive rename, and sample filter

- notDebrid (host-level) no longer burns all keys: stops rotation immediately
  with 5min cooldown instead of cycling through all 9 keys pointlessly
- Remove double provider-blockade: debrid_link_cooldown no longer stacks
  recordProviderFailure + applyProviderBusyBackoff on top of key cooldowns
- Detect timeout cascades: 2+ consecutive transport failures trigger 3min
  cooldown instead of burning remaining keys
- Case-sensitive rename: files with different casing (e.g. lowercase scene
  names) now get properly renamed instead of being skipped as "already matching"
- Extended sample filter: detect -s.mkv suffix and \Sample\ subdirectories
  in auto-rename (already worked in MKV-move)
- Add key status display with state pills in Debrid-Link key stats popup
- Add parseDebridLinkTerminalFailure for fast-fail on exhausted keys
