- Introduced an optional `duration` parameter for catch-up sessions, allowing clients to specify the programme length in minutes. This value is preferred over EPG-derived durations and includes a buffer for provider lag.
- Updated the API views and serializers to accept and process the new `duration` field.
- Enhanced the catch-up proxy implementation to utilize the client-supplied duration, improving playback accuracy.
- Added tests to validate the new duration handling and ensure proper integration with existing functionality.
Add end-to-end catch-up support for XC clients and native apps: provider
proxy with failover and per-viewer session pooling, REST session minting
for tokenless playback URLs, catch-up admin stats, combined connection
stats, and Stats UI with dedicated cards plus websocket updates.
Includes Redis namespace consolidation under timeshift:* (dropping legacy
timeshift_ id prefixes), dedicated catch-up stop by session_id, and
cleaner channel/client metadata split for stats keys.
Closes#133
