Move context from modules to services (#29440)
Since `modules/context` has to depend on `models` and many other
packages, it should be moved from `modules/context` to
`services/context` according to design principles. There is no logic
code change on this PR, only move packages.

- Move `code.gitea.io/gitea/modules/context` to
`code.gitea.io/gitea/services/context`
- Move `code.gitea.io/gitea/modules/contexttest` to
`code.gitea.io/gitea/services/contexttest` because of depending on
context
- Move `code.gitea.io/gitea/modules/upload` to
`code.gitea.io/gitea/services/context/upload` because of depending on
context

Use User.ID instead of User.Name in ActivityPub API for Person IRI (#23823)
Thanks to @trwnh

Close #23802

The ActivityPub id is an HTTPS URI that should remain constant, even if
the user changes their name.

Add context cache as a request level cache (#22294)
To avoid duplicated load of the same data in an HTTP request, we can set
a context cache to do that. i.e. Some pages may load a user from a
database with the same id in different areas on the same page. But the
code is hidden in two different deep logic. How should we share the
user? As a result of this PR, now if both entry functions accept
`context.Context` as the first parameter and we just need to refactor
`GetUserByID` to reuse the user from the context cache. Then it will not
be loaded twice on an HTTP request.

But of course, sometimes we would like to reload an object from the
database, that's why `RemoveContextData` is also exposed.

The core context cache is here. It defines a new context
```go
type cacheContext struct {
	ctx  context.Context
	data map[any]map[any]any
        lock sync.RWMutex
}

var cacheContextKey = struct{}{}

func WithCacheContext(ctx context.Context) context.Context {
	return context.WithValue(ctx, cacheContextKey, &cacheContext{
		ctx:  ctx,
		data: make(map[any]map[any]any),
	})
}
```

Then you can use the below 4 methods to read/write/del the data within
the same context.

```go
func GetContextData(ctx context.Context, tp, key any) any
func SetContextData(ctx context.Context, tp, key, value any)
func RemoveContextData(ctx context.Context, tp, key any)
func GetWithContextCache[T any](ctx context.Context, cacheGroupKey string, cacheTargetID any, f func() (T, error)) (T, error)
```

Then let's take a look at how `system.GetString` implement it.

```go
func GetSetting(ctx context.Context, key string) (string, error) {
	return cache.GetWithContextCache(ctx, contextCacheKey, key, func() (string, error) {
		return cache.GetString(genSettingCacheKey(key), func() (string, error) {
			res, err := GetSettingNoCache(ctx, key)
			if err != nil {
				return "", err
			}
			return res.SettingValue, nil
		})
	})
}
```

First, it will check if context data include the setting object with the
key. If not, it will query from the global cache which may be memory or
a Redis cache. If not, it will get the object from the database. In the
end, if the object gets from the global cache or database, it will be
set into the context cache.

An object stored in the context cache will only be destroyed after the
context disappeared.

Add more linters to improve code readability (#19989)
Add nakedret, unconvert, wastedassign, stylecheck and nolintlint linters to improve code readability

- nakedret - https://github.com/alexkohler/nakedret - nakedret is a Go static analysis tool to find naked returns in functions greater than a specified function length.
- unconvert - https://github.com/mdempsky/unconvert - Remove unnecessary type conversions
- wastedassign - https://github.com/sanposhiho/wastedassign -  wastedassign finds wasted assignment statements.
- notlintlint -  Reports ill-formed or insufficient nolint directives
- stylecheck - https://staticcheck.io/docs/checks/#ST - keep style consistent
  - excluded: [ST1003 - Poorly chosen identifier](https://staticcheck.io/docs/checks/#ST1003) and [ST1005 - Incorrectly formatted error string](https://staticcheck.io/docs/checks/#ST1005)

* WebFinger: Add CORS header and fix Href -> Template for remote interactions

The CORS header is needed due to https://datatracker.ietf.org/doc/html/rfc7033#section-5 and fixes some Peertube <-> Gitea federation issues

* make lint-backend

* Make sure Person endpoint has Content-Type application/activity+json and includes PreferredUsername, URL, and Icon

Setting the correct Content-Type is essential for federating with Mastodon

* Use UTC instead of GMT

* Rename pkey to pubKey

* Make sure HTTP request Date in GMT

* make fmt

* dont drop err

* Make sure API responses always refer to username in original case

Copied from what I wrote on #19133 discussion: Handling username case is a very tricky issue and I've already encountered a Mastodon <-> Gitea federation bug due to Gitea considering Ta180m and ta180m to be the same user while Mastodon thinks they are two different users. I think the best way forward is for Gitea to only use the original case version of the username for federation so other AP software don't get confused.

* Move httpsig algs constant slice to modules/setting/federation.go

* Add new federation settings to app.example.ini and config-cheat-sheet

* Return if marshalling error

* Make sure Person IRIs are generated correctly

This commit ensures that if the setting.AppURL is something like "http://127.0.0.1:42567" (like in the integration tests), a trailing slash will be added after that URL.

* If httpsig verification fails, fix Host header and try again

This fixes a very rare bug when Gitea and another AP server (confirmed to happen with Mastodon) are running on the same machine, Gitea fails to verify incoming HTTP signatures. This is because the other AP server creates the sig with the public Gitea domain as the Host. However, when Gitea receives the request, the Host header is instead localhost, so the signature verification fails. Manually changing the host header to the correct value and trying the veification again fixes the bug.


* Revert "If httpsig verification fails, fix Host header and try again"

This reverts commit f53e46c721.

The bug was actually caused by nginx messing up the Host header when reverse-proxying since I didn't have the line `proxy_set_header Host $host;` in my nginx config for Gitea.

* Go back to using ap.IRI to generate inbox and outbox IRIs

* use const for key values

* Update routers/web/webfinger.go

* Use ctx.JSON in Person response to make code cleaner

* Revert "Use ctx.JSON in Person response to make code cleaner"

This doesn't work because the ctx.JSON() function already sends the response out and it's too late to edit the headers.

This reverts commit 95aad98897.

* Use activitypub.ActivityStreamsContentType for Person response Content Type

* Don't multiply Federation.MaxSize by 1<<20 twice

* Add more better comments

* Fix failing ActivityPubMissingPerson test

We now use ctx.ContextUser so the message printed out when a user does not exist is slightly different

* make generate-swagger

For some reason I didn't realize that /templates/swagger/v1_json.tmpl was machine-generated by make generate-swagger... I've been editing it by hand for three months! 🤦

* More code cleanup

* Update go-ap to fix empty liked collection and removed unneeded HTTP headers
