feat: phone webhook integration (callstart/callend on port 8081)

- New webhook server on port 8081 for phone system (PBX)
- Endpoints: GET/POST /{extension}/callstart and /{extension}/callend
- New 'phone_extension' field on users (Durchwahl)
- Only activates when user is anwesend or homeoffice (AIDA)
- Sets WLED to phone_active color (red) on callstart
- Restores previous Teams/AIDA color on callend
- Polling skips WLED update while phone is active
- Dashboard shows phone badge when user is in a call
- New color rule 'phone_active' (configurable via web UI)
