* Fix IP address rate limit

* CHANGELOG

* Tune getIpHash

fix #8756

* remove unnecessary if

`Array.prototype.some` already returns a boolean so an if to return
true or false is completely unnecessary in this case.

* perf: use count instead of find

When using `count` instead of `findOneBy`, the data is not
unnecessarily loaded.

* remove duplicate null check

The variable is checked for null in the lines above and the function
returns if so. Therefore, it can not be null at this point.

* simplify `getJsonSchema`

Because the assigned value is `null` and the used keys are only
shallow, use of `nestedProperty.set` seems inappropriate. Because the
value is not read, the initial for loop can be replaced by a `for..in`
loop.

Since all keys will be assigned `null`, the condition of the ternary
expression in the nested function will always be true. Therefore the
recursion case will never happen. With this the nested function can be
eliminated.

* remove duplicate condition

The code above already checks `dragging` and returns if it is truthy.
Checking it again later is therefore unnecessary.

To make this more obvious the `return` is removed in favour of using
an if...else construct.

* remove impossible "unknown" time

The `ago` variable will always be a number and all non-negative numbers
are already covered by other cases, the negative case is handled with
`future` so there is no case when `unkown` could be achieved.

* preload app css

fix #8744

* fix: emits use ev instead of e

* fix: errors use err instead of e

* fix: replace use of data where possible

* fix: events use evt instead of e

* fix: use strict equals

* fix: use emoji instead of e

* fix: vue lints

Misskey does not know if two remote users are following each other.
Because ActivityPub actions would otherwise fail on followers only
notes, we have to assume that two remote users are following each other
when an interaction about a remote note occurs.

* simplify temporary files for thumbnails

Because only a single file will be written to the directory, creating a
separate directory seems unnecessary. If only a temporary file is created,
the code from `createTemp` can be reused here as well.

* refactor: deduplicate code for temporary files/directories

To follow the DRY principle, the same code should not be duplicated
across different files. Instead an already existing function is used.

Because temporary directories are also create in multiple locations,
a function for this is also newly added to reduce duplication.

* fix: clean up identicon temp files

The temporary files for identicons are not reused and can be deleted
after they are fully read. This condition is met when the stream is closed
and so the file can be cleaned up using the events API of the stream.

* fix: ensure cleanup is called when download fails

* fix: ensure cleanup is called in error conditions

This covers import/export queue jobs and is mostly just wrapping all
code in a try...finally statement where the finally runs the cleanup.

* fix: use correct type instead of `any`

* fix(client): refactor widgets and fix lint issues

* Apply review suggestions from @Johann150
