[MODERATION] restore redirect on unblock

 ctx.RedirectToFirst(ctx.FormString("redirect_to"), ctx.ContextUser.HomeLink())

was replaced by

 ctx.JSONOK()

in 128d77a Following up fixes for "Fix inconsistent user profile layout across tabs" (go-gitea#25739)

thus changing the behavior (nicely spotted by the tests). This
restores it.

[MODERATION] Block adding collaborators

- Ensure that the doer and blocked user cannot add each other as
collaborators to repositories.
- The Web UI gets an detailed message of the specific situation, the API
gets an generic Forbidden code.
- Unit tests has been added.
- Integration testing for Web and API has been added.
- This commit doesn't introduce removing each other as collaborators on
the block action, due to the complexity of database calls that needs to
be figured out. That deserves its own commit and test code.

[MODERATION] Remove blocked user collaborations with doer

- When the doer blocks an user, who is also an collaborator on an
repository that the doer owns, remove that collaboration.
- Added unit tests.
- Refactor the unit test to be more organized.

[MODERATION] QoL improvements (squash)

- Ensure that organisations cannot be blocked. It currently has no
effect, as all blocked operations cannot be executed from an
organisation standpoint.
- Refactored the API route to make use of the `UserAssignmentAPI`
middleware.
- Make more use of `t.Run` so that the test code is more clear about
which block of code belongs to which test case.
- Added more integration testing (to ensure the organisations cannot be
blocked and some authorization/permission checks).

[MODERATION] Refactor integration testing (squash)

- Motivation for this PR is that I'd noticed that a lot of repeated
calls are happening between the test functions and that certain tests
weren't using helper functions like `GetCSRF`, therefor this refactor of
the integration tests to keep it: clean, small and hopefully more
maintainable and understandable.
- There are now three integration tests: `TestBlockUser`,
`TestBlockUserFromOrganization` and `TestBlockActions` (and has been
moved in that order in the source code).
- `TestBlockUser` is for doing blocking related actions as an user and
`TestBlockUserFromOrganization` as an organisation, even though they
execute the same kind of tests they do not share any database calls or
logic and therefor it currently doesn't make sense to merge them
together (hopefully such oppurtinutiy might be presented in the future).
- `TestBlockActions` now contain all tests for actions that should be
blocked after blocking has happened, most tests now share the same doer
and blocked users and a extra fixture has been added to make this
possible for the comment test.
- Less code, more comments and more re-use between tests.

[MODERATION] Fix network error (squash)

- Fix network error toast messages on user actions such as follow and
unfollow. This happened because the javascript code now expects an JSON
to be returned, but this wasn't the case due to
cfa539e590127b4953b010fba3dea21c82a1714.
- The integration testing has been adjusted to instead test for the
returned flash cookie.

[MODERATION] Modernize frontend (squash)

- Unify blocked users list.
- Use the new flex list classes for blocked users list to avoid using
the CSS helper classes and thereby be consistent in the design.
- Fix the modal by using the new modal class.
- Remove the icon in the modal as looks too big in the new design.
- Fix avatar not displaying as it was passing the context where the user
should've been passed.
- Don't use italics for 'Blocked since' text.
- Use namelink template to display the user's name and homelink.
