Expose quote posting in the api as a feature.
Copies what the quote post PR for pleroma does to allow external clients to enable and disable features based on the feature-set of the instance.
As far as I am aware, akkoma doesn't allow you to disable quote posting, so this doesn't need anything fancy and it's just a hard on switch.
I tried to get one for the bubble tl to work also, but I'm not quite sure how to do it so that it switches off the feature when the bubble tl is disabled. I would argue that it could and ideally should be done as well though.
I also discovered a pretty tame bug in the testing of it, that deleting the DB entry for the bubble tl does not stop the bubble TL from actually working and it will continue to display the panel on the about page, I'll just leave it as a note here.

E.g. Flag activities have an array of objects
We prune the activity when NONE of the objects can be found
Note that the cost of finding and deleting these is ~4x higher than finding and deleting the non-array ones
Only string:
Delete on activities (cost=506573.48..506580.38 rows=0 width=0)
Only Array:
Delete on activities (cost=3570359.68..4276365.34 rows=0 width=0)
(They are still executed separately, so the total cost is the sum of the two)
We add an option to also prune remote activities who don't have existing objects any more they reference.
Rn, we only check for activities who only reference one object, not an array or embeded object.
By default Postgresql first restores the data and then the indexes when dumping and restoring the database.
Restoring index activities_visibility_index took a very long time.
users_ap_id_COALESCE_follower_address_index was later added because having this could speed up the restoration tremendously.
The problem now is that restoration apparently happens in alphabetical order, so this new index wasn't created yet
by the time activities_visibility_index needed it.
There were several work-arounds which included more complex steps during backup/restore.
By renaming this index, it should be restored first and thus activities_visibility_index can make use of it.
This speeds up restoration significantly without requiring more complex or unexpected steps from people.
I added info about installing front ends from the development branch
I also rearanged the list of exceptions (what's different than "normal" installation)
so the order is closer to how you'd encounter things in the installation docs + small fixes
