Migrate to v4

Caution

Before updating to v4 it's reccomended to stop/complete all your downloads and backup all your templates and cron jobs!

yt-dlp-web-ui v4 introduces many changes to the underlying code and configuration management.

The first thing was ditch file based session storing for a streamlined approach with bolt. This ensures better performance, better migrations and a single source of thruth for all the backend state management.

The config file was also revamped, now more structured and clinger to field-drive-configuration (FDC) - supporting:

• YAML
• TOML
• ENV
