feat: add CLI command 'admin user create-authorized-integration' (#12299)

Allows the creation of an authorized integration as a Forgejo administrator, either for development testing or to support server-automation.  Clipping out the CLI config options, looks like:

```
NAME:
   forgejo admin user create-authorized-integration - Create an authorized integration for a specific user

USAGE:
   forgejo admin user create-authorized-integration [options]

OPTIONS:
   --username string, -u string                               Username
   --issuer string                                            JWT issuer ('iss' claim), example: https://forgejo.example.org/api/actions
   --claim-eq string=string [ --claim-eq string=string ]      Zero-or-more claim equality checks, formatted as claim=value, example: "actor=someuser"
   --claim-glob string=string [ --claim-glob string=string ]  Zero-or-more claim glob checks, formatted as claim=value, example: "sub=repo:forgejo/*:pull_request"
   --scope string [ --scope string ]                          One-or-more scopes to apply to access token, examples: "all", "read:issue", "write:repository" (default: "all")
   --repo string [ --repo string ]                            Zero-or-more specific repositories that can be accessed, or "all" to allow access to all repositories, example: "owner1/repo1" (default: "all")
```

As an example, this will create an authorized integration that will permit Codeberg's Forgejo Actions to generate trusted JWTs that can access the local user `mfenniak`:
```bash
$ ./forgejo admin user create-authorized-integration \
    --username mfenniak \
    --issuer https://codeberg.org/api/actions \
    --claim-eq sub=repo:mfenniak/forgejo-runner-testrepo:pull_request \
    --scope read:user

{
  "message": "Authorized integration was successfully created.",
  "issuer": "https://codeberg.org/api/actions",
  "audience": "u:1:c97d83bc-fa4e-4db3-b898-414cd5b6ce33",
  "claim_rules": [
    {
      "description": "\"sub\" = \"repo:mfenniak/forgejo-runner-testrepo:pull_request\"",
      "claim": "sub",
      "compare": "eq",
      "value": "repo:mfenniak/forgejo-runner-testrepo:pull_request"
    }
  ]
}
```

The output is a JSON document to aid in use in automation.  The `audience` field is the audience generated by Forgejo that must be used by the remote to generate the JWT.  Continuing this example to the client-side, a matching Forgejo Action like this in the `mfenniak/forgejo-runner-testrepo` repo, for a `pull_request` event, then it will be able to access the Forgejo server that the authorized integration was created on like this:

```yaml
on:
  pull_request:

enable-openid-connect: true

jobs:
  job1:
    runs-on: docker
    steps:
      - name: Fetch JWT
        id: jwt
        run: |
          set -eux -o pipefail
          set +x
          jwt=$(curl --fail \
            -H "Authorization: bearer $ACTIONS_ID_TOKEN_REQUEST_TOKEN" "$ACTIONS_ID_TOKEN_REQUEST_URL&audience=u:1:c97d83bc-fa4e-4db3-b898-414cd5b6ce33" \
            | jq -r ".value")
          echo "::add-mask::$jwt"
          set -x
          echo "jwt=$jwt" >> $FORGEJO_OUTPUT

      - name: API call to Forgejo
        run: |
          curl \
            -v --fail \
            -H "Authorization: bearer ${{ steps.jwt.outputs.jwt }}" \
            "https://example.org/api/v1/user" | jq
```

CLI command is tested manually.  Supporting functions have associated unit tests.

## Checklist

The [contributor guide](https://forgejo.org/docs/next/contributor/) contains information that will be helpful to first time contributors. All work and communication must conform to Forgejo's [AI Agreement](https://codeberg.org/forgejo/governance/src/branch/main/AIAgreement.md). There also are a few [conditions for merging Pull Requests in Forgejo repositories](https://codeberg.org/forgejo/governance/src/branch/main/PullRequestsAgreement.md). You are also welcome to join the [Forgejo development chatroom](https://matrix.to/#/#forgejo-development:matrix.org).

### Tests for Go changes

- I added test coverage for Go changes...
  - [x] in their respective `*_test.go` for unit tests.
  - [ ] in the `tests/integration` directory if it involves interactions with a live Forgejo server.
- I ran...
  - [x] `make pr-go` before pushing

### Documentation

- [ ] I created a pull request [to the documentation](https://codeberg.org/forgejo/docs) to explain to Forgejo users how to use this change.
- [x] I did not document these changes and I do not expect someone else to do it.
    - CLI update should be automatic in docs -- more detailed Authorized Integration documentation is on my project plan.

### Release notes

- [x] This change will be noticed by a Forgejo user or admin (feature, bug fix, performance, etc.). I suggest to include a release note for this change.
- [ ] This change is not visible to a Forgejo user or admin (refactor, dependency upgrade, etc.). I think there is no need to add a release note for this change.

// Generates the `aud` claim that the remote JWT generator must use to match this authorized integration. The `aud`
// claim is an arbitrary value in a JWT claim, but Forgejo is faced with a few hard and soft requirements:
//
// - Hard requirement: each authorized integration must have a unique `aud`, as it is used to find the DB record that
// authenticates a request.
// - If authentication is failing, being able to inspect the `aud` claim can be useful to identify the intent.
// - Inspection should have a stable meaning -- eg. if it included the username, and the user was renamed, the `aud`
// value which can't be changed would continue to reference the old username causing confusion when inspecting it.
// - Forgejo & GitHub Actions uses a URL $ACTIONS_ID_TOKEN_REQUEST_URL&audience=... to generate a JWT for the running
// action, so it should only consist of safe characters for URL encoding.
// - It should be relatively short, as it's encoded into the JWT and increases its size.
//
// Meeting these requirements decently well is a combination of the owner's ID, a guid, and a "u:" prefix that makes the
// fact that it's an `aud` claim value a little bit identifiable.
