jellyseerr: add option to auto-import users

"import_existing" option in settings enables an every 5-minute daemon
which loops through users and imports them to Jellyseerr and copies
contact info, if necessary. Also sets new API client flag
AutoImportUsers, which decides whether to automatically import non-existent users in
it's various methods.

also cleaned up the various daemons in the software, most now using the
GenericDaemon struct and just providing a new constructor.

broken page loop in jellyseerr client also fixed.
