* Move admin flag from person to local_user (fixes#3060)
The person table is for federated data, but admin flag can only

table. This will also prevent the federation code from accidentally
overwriting the admin flag

* Change recipient id to list param
* Remove TypedBuilder from db_views and db_views_actor
* Split activity table into sent and received parts (fixes#3103)
The received activities are only stored in order to avoid processing
the same incoming activity multiple times. For this purpose it is
completely unnecessary to store the data. So we can split the
table into sent_activity and received_activity parts, where
only sent_activity table needs to store activity data. This should
reduce storage use significantly.
Also reduces activity storage duration to three months, we can reduce
this further if necessary.
Additionally the id columns of activity tables are removed because
they are completely unused and risk overflowing (fixes#3560).

* Fix handling of follows addressed to single value
* Switch to deserialize_skip_error for Follow to
* Also use deserialize_skip_error for AcceptFollow and UndoFollow
* actually import deserialize_skip_error
This field is unnecessary because we already set a default language
with the same logic if none is passed in CreatePost. So if the user
doesnt set a post language, it should simply be passed as None. This
also has the advantage that it works with clients that dont support
language tags.
Technically not a breaking change because its optional, but better
be safe.

* Fix listing type default value
The listing type parameter is only meant for the frontpage, but is
also applied inside of communities. The result is that this call
returns nothing, because it defaults to ListingType::Local:
https://fedibb.ml/api/v3/post/list?community_id=3
It needs to be called like this to get any posts:
https://fedibb.ml/api/v3/post/list?community_id=3&type_=All
This is clearly not expected behaviour, when a community is
specified, the listing type should default to All.
