feat: lib updates and more (#1187)

This PR performs the following changes:

- update python in Dockerfile
- updates all python libraries (including Django)
- makes md5sum calculation redundant by default
- updates Postgresql used in Docker. For new installations this is ok. For existing ones this is backwards incompatible, and restore through pg_dump+pg_restore has to be performed in order to utilize Postgres 17 (since its not compatible with previous versions and will complain)
- fixes issues with HLS, and adds test to ensure they won't happen again
- allows . and @ in usernames
