feat(server,web): system config for admin (#959)

* feat: add admin config module for user configured config, uses it for ffmpeg

* feat: add api endpoint to retrieve admin config settings and values

* feat: add settings panel to admin page on web (wip)

* feat: add api endpoint to update the admin config

* chore: re-generate openapi spec after rebase

* refactor: move from admin config to system config naming

* chore: move away from UseGuards to new @Authenticated decorator

* style: dark mode styling for lists and fix conflicting colors

* wip: 2 column design, no edit button

* refactor: system config

* chore: generate open api

* chore: rm broken test

* chore: cleanup types

* refactor: config module names
