feat: link commits, branches and pull requests to tickets

A project can turn on a webhook for GitHub, Gitea or GitLab. Pushes and
pull or merge requests that name a ticket key show on that ticket under
Desarrollo, with the state of each pull request; the secret is shown and
rotated from the project settings.
