## Summary
This PR adds support for updating pull mirror authentication via the
repository edit API and UI.
It introduces new mirror authentication fields in _EditRepoOption_,
updates the API logic to safely handle partial credential updates, and
fixes the web settings flow so that the existing remote username is
preserved when only the password is changed.
### What changed
- added _auth_username_, _auth_password_, and _auth_token_ to
EditRepoOption
- updated the repository edit API to apply mirror auth changes via
_updateMirror_
- preserved existing username/password when only part of the auth
payload is provided
- used oauth2 as the default username when _auth_token_ is provided
- kept stored mirror URLs sanitized in DB and API responses
- updated Swagger schema for the new API fields
- added API integration tests for password-only and token-only updates
- added a web settings test to ensure username preservation on partial
updates
## Why
Some use cases require automated synchronization of pull mirrors, for
example in CI/CD pipelines or integrations with external systems.
At the same time, many organizations enforce security policies that
require periodic token rotation (e.g., monthly).
Currently, mirror credentials can only be updated via the UI, which
makes automation difficult.
## This change enables:
- automated token rotation
- avoiding manual updates via the UI
- easier integration with secret management systems
## Testing
- added integration coverage for mirror auth updates via _PATCH
/api/v1/repos/{owner}/{repo}_
- added web settings tests for password-only updates preserving the
existing username
## Result
Ability to automate auth update

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
Just like `models/unittest`, the testing helper functions should be in a
separate package: `contexttest`
And complete the TODO:
> // TODO: move this function to other packages, because it depends on
"models" package
There are too many files under `routers/web/repo` and the file
`routers/web/repo/setting.go` is too big.
This PR move all setting related routers' body functions under
`routers/web/repo/setting` and also split `routers/web/repo/setting.go`
