Requires that all outbound network connections made by migrations & mirroring be performed over encrypted communication channels. As those communication channels (HTTPS and SSH) have their own built-in protections against DNS rebinding (TLS certificate validation and SSH host key validation), DNS rebinding attacks become ineffective as a means to redirect Forgejo to pull-from or push-to unexpected remotes with mirrors.
`[migrations].ALLOW_UNENCRYPTED` is a new setting which defaults to false, and can be set to `true` to restore access to unencrypted remotes. The risks associated with it are documented in `app.example.ini` and will be transferred into the docs repo.
**Breaking:** Existing mirrors configured against `http://` and `git://` protocols will fail, with "unencrypted transfer protocol, remote cannot be validated". It is recommended that those mirrors be changed to encrypted protocols. `[migrations].ALLOW_UNENCRYPTED` may be set to `true` to revert to the previous behaviour, accepting the risks documented here.

System administrators can determine which hosts can be accessed by Forgejo for git mirroring via the config settings `[migrations].ALLOWED_DOMAINS`, `...BLOCKED_DOMAINS`, and `....ALLOW_LOCALNETWORKS`. However, there were edge cases where these settings were ineffective:
- Config entries were only checked when mirrors were initially configured, and not later when a mirror pull/push occurred. DNS changes, or server configuration changes, could cause a previously safe URL to no longer be safe. These settings are now re-checked on every mirror pull/push.
- When accessing a git repository over http, git would follow HTTP redirects, allowing a violation of the `[migrations]` config entries. The git option `http.followRedirects=false` is now set to prevent git from following these redirects.
- When performing Git LFS synchronization, it was assumed that the git URL passing migration URL checks was sufficient protection. Specifically for pull mirrors which allow the usage of "Advanced settings" -> "LFS endpoint" to configure a separate LFS endpoint, these settings were never enforced, and for all mirrors they would have been subject to not being rechecked if the DNS had changed since configured. LFS mirroring now uses an HTTP client that enforces the `[migrations]` config settings.
**Breaking:** If a repository mirror that depends on HTTP redirects will no longer work.
For example, if you've mirrored a repository from a Forgejo instance at `https://example.com/OWNER/REPO.git` and the repository or owner are renamed, Forgejo will provide an HTTP redirect that continues to allow git operations to work at the old URL. Due to this redirect prohibition, this mirror will no longer work.

### Context
Following the feedback in forgejo/discussions#170 (and my ambitious attempt in forgejo/forgejo#10985), it appears that having an easy-to-use factory package would greatly help get rid of the global fixtures.
I think that the global fixtures are quite harmful (recent example: https://codeberg.org/forgejo/forgejo/pulls/9906#issuecomment-10826066):
- hard to write (contributor must know where to add them)
- hard to change (may break some unrelated tests)
- hard to review (not located near the test code)
- they require the tests to execute sequentially
### Proposed way forward
The `forgery` package (the name represents faking/crafting and sounds good with Forgejo) is meant to replace global yaml fixtures with local go factories. The forgery can currently:
- create users
- create repos
- create organisations
This allowed me to drop `CreateDeclarativeRepoWithOptions` (and deprecate `CreateDeclarativeRepo`).
I think that further changes should be delayed to other PRs (I have a local branch to create `Project`)

Fixes#9629.
New pull mirrors have credentials stored encrypted in the database, the same as push mirrors, rather than in the repository's `config` file. `git fetch` on the pull mirror is updated to use the credential store. Pull mirrors will have their credentials migrated to the encrypted storage in the database as they're synced or otherwise accessed via the web UI.

To make sure that the code stays maintainable, I added the `importas` linter to ensure that the imports for models and services stay consistent.
I realised that this might be needed after finding some discrepancies between singular/plural naming, and, especially in the case of the `forgejo.org/services/context` package, multiple different aliases like `gitea_ctx`, `app_context` and `forgejo_context`. I decided for `app_context`, as that seems to be the most commonly used naming.

Replace the anti-CSRF token with a [cross origin protection by Go](https://go.dev/doc/go1.25#nethttppkgnethttp) that uses a stateless way of verifying if a request was cross origin or not. This allows is to remove al lot of code and replace it with a few lines of code and we no longer have to hand roll this protection. The new protection uses indicators by the browser itself that indicate if the request is cross-origin, thus we no longer have to take care of ensuring the generated CSRF token is passed back to the server any request by the the browser will have send this indicator.

## Purpose
This is a refactor toward building an abstraction over managing git
repositories.
Afterwards, it does not matter anymore if they are stored on the local
disk or somewhere remote.
## What this PR changes
We used `git.OpenRepository` everywhere previously.
Now, we should split them into two distinct functions:
Firstly, there are temporary repositories which do not change:
```go
git.OpenRepository(ctx, diskPath)
```
Gitea managed repositories having a record in the database in the
`repository` table are moved into the new package `gitrepo`:
```go
gitrepo.OpenRepository(ctx, repo_model.Repo)
```
Why is `repo_model.Repository` the second parameter instead of file
path?
Because then we can easily adapt our repository storage strategy.
The repositories can be stored locally, however, they could just as well
be stored on a remote server.
## Further changes in other PRs
- A Git Command wrapper on package `gitrepo` could be created. i.e.
`NewCommand(ctx, repo_model.Repository, commands...)`. `git.RunOpts{Dir:
repo.RepoPath()}`, the directory should be empty before invoking this
method and it can be filled in the function only. #28940
- Remove the `RepoPath()`/`WikiPath()` functions to reduce the
possibility of mistakes.
