API: Use references in shifts list, added shift types endpoints

[MyIgel]

• Use references in shifts list instead of always returning full data sets (breaking change in beta API)
  This change is definitely needed to improve the file size for example for room shift endpoints as they are currently too big with tons of redundant datasets
• Group entries by angeltypes to show additional states like freeloaded (breaking response structure change)
• Renamed users tshirt to tshirt_size (breaking response structure)
• Added shift types endpoints (list and shifts by shift type) to retrieve them
• Added description to location
• Fixed model nullable, casts and default values
• Improved api tests error messages when response does not match the spec

[xuwhite]

• in references names in addition to ids would be helpful
• change title of shifts to name
• please change type to angeltype in shiftentries

{
  "entries": [
    {
      "users": [],
      "type": { "id": 1 },
      "needs": 2
    }
  ]
}

I don't get all shifts with the angeltype from /angeltypes/{id}/shifts

4 is not equal 72

Edit: Moved to issue #1392

[xuwhite]

please add freeloaded to shifts

Please change tshirt to goodie in /users/{id}

[xuwhite]

please add at least Description to locations (like angeltypes)

[xuwhite]

please fix the comments above

[MyIgel]

please add freeloaded to shifts

@xuwhite The current model does not have a good place for that without restructuring

Please change tshirt to goodie in /users/{id}

Thats the tshirt size as per documentation, i could change the key to tshirt_size to make it clearer 🤷

please add at least Description to locations (like angeltypes)

than I would prefer to not show the user in a freeloaded shift

[MyIgel]

please add freeloaded to shifts

Its implemented and needed a bigger change (grouping entries by angeltype and then user to show that state) but here it is
