feat(actions): add runs, jobs, and logs commands

Implement tea actions commands to view workflow runs and logs using
the Gitea 1.25 API endpoints directly. This adds:
- `tea actions runs` - list workflow runs for a repository
- `tea actions jobs <run-id>` - list jobs for a specific run
- `tea actions logs <job-id>` - display logs for a specific job

Also adds a new `modules/api` package for making raw authenticated
HTTP requests to Gitea API endpoints not yet supported by the go-sdk.

Closes #1
