jellyseerr already did this, but it's been standardised a little more.
Mediabrowser uses it's own genericErr function and error types due to
being a separate package, while jellyseerr and ombi now share errors
defined in common/.
NOTE: If you previously used the Ombi integration, New ombi users
won't be created until you set this up.
Ombi settings can be added to a profile in Settings > User Profiles.
The "Modify settings" options will now apply to ombi if the selected
profile has ombi settings.
