Bug Fix: Stats page "Active Stream" dropdown not updating when a stream switch occurs

 - Fixed manual stream selection from the Stats page not enforcing M3U profile connection limits in multi-worker deployments. When a non-owning worker handled the `change_stream` request it correctly packaged `stream_id` and `m3u_profile_id` into the Redis pubsub message, but the owning worker's pubsub handler only consumed `url` and `user_agent` silently dropping both IDs before calling `stream_manager.update_url()`. Because `update_url` only calls `update_stream_profile()` when a `stream_id` is provided, the `profile_connections` counter was never updated after the switch, causing subsequent capacity checks to see incorrect counts and bypass the full-profile guard. The handler now extracts `stream_id` and `m3u_profile_id` from the event and forwards them to `update_url()`. The bug did not affect single-worker / dev-mode deployments because the owning worker handles those requests directly without pubsub.
 - Fixed the `next_stream` rotation endpoint applying the same class of bug: `get_stream_info_for_switch()` was called and returned `m3u_profile_id`, but the result was dropped when forwarding to `ChannelService.change_stream_url()`, so `update_stream_profile()` was never called and `profile_connections` counters were not updated after an automatic stream rotation.
 - Fixed stream switch metadata (`url`, `user_agent`, `stream_id`, `m3u_profile`) being written to Redis before the switch was confirmed to succeed. If the switch failed, URL unchanged or exception during teardown, Redis described a URL not actually in use. Metadata is now written only after `update_url()` returns `True`; on failure the owner writes `stream_manager.url` back as the ground truth. The non-owner no longer pre-writes metadata at all, all needed info is carried in the pubsub payload and written by the owner after confirmation.
+- Fixed the Stats page "Active Stream" dropdown not updating when a stream switch occurs. The card was matching the active stream by comparing the URL stored in Redis against stream URLs from the database, which failed silently when the stored URL was a transformed/rewritten value that didn't substring-match the original. The dropdown now matches by `stream_id` (the authoritative value already present in the stats payload) and re-runs only when `stream_id` changes, so the normal polling interval drives updates with no extra renders.
 - Fixed uploading a local M3U file with no expiration date set sending the string `"null"` as the `exp_date` field in the `FormData` request, causing a 400 validation error from the API. Null/undefined values are now skipped when building the `FormData` body, matching the behaviour already present in the update path.
 - Fixed `PATCH /api/channels/channels/edit/bulk/` returning a 500 error when the request body included a `streams` list. The bulk edit handler was iterating `validated_data` directly and calling `setattr(channel, "streams", value)`, which Django prohibits on ManyToMany fields. Also added an `@extend_schema` decorator so the Swagger UI correctly documents the endpoint as accepting a JSON array and shows the `streams` field. (Fixes #883)
 - Fixed several incorrect or incomplete OpenAPI (`@extend_schema`) schemas across the API:
