[BUG] KeyError: 'tvdb_id' when processing Emby webhook if tvdb_id is missing from TMDB response

[bison529]

Describe the bug

When processing a webhook from Emby for shows like The Walking Dead (e.g., S02E03 or S02E04), the application crashes with a KeyError: 'tvdb_id'.

It appears that the method app.providers.tmdb.tv_with_seasons(...) does not always return a tvdb_id, but the code assumes its presence unconditionally.

---

Full traceback:

KeyError: 'tvdb_id'
File "/yamtrack/integrations/webhooks/base.py", line 65, in _process_tv
  tvdb_id = app.providers.tmdb.tv_with_seasons(media_id, [season_number])["tvdb_id"]

Steps to reproduce

1. Connect Emby with the webhook endpoint /webhook/emby/...
2. Play an episode from a TV series that does not include tvdb_id in the TMDB response
3. The webhook triggers a 500 Internal Server Error
4. The log shows a KeyError related to the missing tvdb_id

Expected behavior

The code should handle the case when tvdb_id is missing gracefully, avoiding a hard crash.

Environment

• Django: 5.2.2
• Python: 3.12
• Container: Custom Docker image (built from project Dockerfile)
• DB: PostgreSQL 15

Thanks for the great work on Yamtrack 🙌 — this issue just needs a bit of defensive coding to improve webhook stability.
