Maintenance update (#7)

- Use modern tooling uv and bun
- Various changes to work with latest PyAV and PIL that have changed their API
- Improved image, video and document previews (uses AVIF, renders AVIF/HEIC/videos in HDR, faster processing)
- Fix a server hang in some cases where a folder was moved or renamed
- Log exceptions instead of only returning 500 response to client
- Log timing of preview generation functions
- Default to quality 50 in previews (previously 40)
