- all models have a "title" field, and that's the default sorting field, however this is not being indexed as such for the models, except where explicitly specified (Anime and Manga models)
- genre filtering
- added unapproved filtering
- fixed sfw filtering
- fixed kids filtering
- fixed deprecation warnings as of php 8.1
- DateTime ctor can't take `null` anymore as first param
- preg_replace doesn't accept `null` values as `$subject`
- fixed failed items indexer (the --failed option of indexers) -- it didn't load the correct file making it impossible to retry the indexing
- changed the document schema for search indexed anime/manga
- added `approved` field to them
- staging will require a reimport into TypeSense
- the central filtering system will now process `sfw` and `unapproved` filters, so they will be applied implicitly through the `filter` model scope method.
