Last known backend change for #11311, fixing up some loose ends on the repository APIs related to repo-specific access tokens.
Adds automated testing, and aligns permissions where necessary, to ensure that repo-specific access tokens can't change the administrative state of the repositories that they are limited to.
Repo-specific access tokens cannot be used to:
- convert a mirror into a normal repo,
- create a new repository from a template,
- transfer ownership of a repository
- create a new repository (already protected, but test automation added),
- delete a repository (already protected, but test automation added),
- editing a repository's settings (already protected, but test automation added).
**Breaking**: The template generation (`POST /repos/{template_owner}/{template_repo}/generate`) and repository deletion (`DELETE /repos/{username}/{reponame}`) APIs have been updated to require the same permission scope as creating a new repository. Either `write:user` or `write:organization` is required, depending on the owner of the repository being created or deleted.

- Add `binding:"In(...)"` to the `default_merge_style` and `default_update_style` fields to only accept recognized merge and update styles.
- Resolves https://codeberg.org/forgejo/forgejo/issues/7389
- Added integration test for the API (`binding` works in the exact same way for the API and web routes).

With this option, it is possible to require a linear commit history with
the following benefits over the next best option `Rebase+fast-forward`:
The original commits continue existing, with the original signatures
continuing to stay valid instead of being rewritten, there is no merge
commit, and reverting commits becomes easier.
Closes#24906
## Changes
- Adds the following high level access scopes, each with `read` and
`write` levels:
- `activitypub`
- `admin` (hidden if user is not a site admin)
- `misc`
- `notification`
- `organization`
- `package`
- `issue`
- `repository`
- `user`
- Adds new middleware function `tokenRequiresScopes()` in addition to
`reqToken()`
- `tokenRequiresScopes()` is used for each high-level api section
- _if_ a scoped token is present, checks that the required scope is
included based on the section and HTTP method
- `reqToken()` is used for individual routes
- checks that required authentication is present (but does not check
scope levels as this will already have been handled by
`tokenRequiresScopes()`
- Adds migration to convert old scoped access tokens to the new set of
scopes
- Updates the user interface for scope selection

## tokenRequiresScopes Design Decision
- `tokenRequiresScopes()` was added to more reliably cover api routes.
For an incoming request, this function uses the given scope category
(say `AccessTokenScopeCategoryOrganization`) and the HTTP method (say
`DELETE`) and verifies that any scoped tokens in use include
`delete:organization`.
- `reqToken()` is used to enforce auth for individual routes that
require it. If a scoped token is not present for a request,
`tokenRequiresScopes()` will not return an error
## TODO
- [x] Alphabetize scope categories
- [x] Change 'public repos only' to a radio button (private vs public).
Also expand this to organizations
- [X] Disable token creation if no scopes selected. Alternatively, show
warning
- [x] `reqToken()` is missing from many `POST/DELETE` routes in the api.
`tokenRequiresScopes()` only checks that a given token has the correct
scope, `reqToken()` must be used to check that a token (or some other
auth) is present.
- _This should be addressed in this PR_
- [x] The migration should be reviewed very carefully in order to
minimize access changes to existing user tokens.
- _This should be addressed in this PR_
- [x] Link to api to swagger documentation, clarify what
read/write/delete levels correspond to
- [x] Review cases where more than one scope is needed as this directly
deviates from the api definition.
- _This should be addressed in this PR_
- For example:
```go
m.Group("/users/{username}/orgs", func() {
m.Get("", reqToken(), org.ListUserOrgs)
m.Get("/{org}/permissions", reqToken(), org.GetUserOrgsPermissions)
}, tokenRequiresScopes(auth_model.AccessTokenScopeCategoryUser,
auth_model.AccessTokenScopeCategoryOrganization),
context_service.UserAssignmentAPI())
```
## Future improvements
- [ ] Add required scopes to swagger documentation
- [ ] Redesign `reqToken()` to be opt-out rather than opt-in
- [ ] Subdivide scopes like `repository`
- [ ] Once a token is created, if it has no scopes, we should display
text instead of an empty bullet point
- [ ] If the 'public repos only' option is selected, should read
categories be selected by default

This PR adds the support for scopes of access tokens, mimicking the
design of GitHub OAuth scopes.
The changes of the core logic are in `models/auth` that `AccessToken`
struct will have a `Scope` field. The normalized (no duplication of
scope), comma-separated scope string will be stored in `access_token`
table in the database.
In `services/auth`, the scope will be stored in context, which will be
used by `reqToken` middleware in API calls. Only OAuth2 tokens will have
granular token scopes, while others like BasicAuth will default to scope
`all`.
A large amount of work happens in `routers/api/v1/api.go` and the
corresponding `tests/integration` tests, that is adding necessary scopes
to each of the API calls as they fit.
- [x] Add `Scope` field to `AccessToken`
- [x] Add access control to all API endpoints
- [x] Update frontend & backend for when creating tokens
- [x] Add a database migration for `scope` column (enable 'all' access
to past tokens)
I'm aiming to complete it before Gitea 1.19 release.
