🧪 How to Test (if required)

1. Verify if timelapse api can be filtered by from/to date, time and timezone:

Examples:
http://localhost:8000/api/webcams/67/timelapse/

http://localhost:8000/api/webcams/67/timelapse/?from=2026-04-19&to=2026-04-19&time_from=08:00&time_to=18:00&timezone=America/Vancouver

http://localhost:8000/api/webcams/67/timelapse/?timezone=America/Vancouver

with or without parameter, verify if the response can be filtered out as expected.
