fix(developers): add Mattermost team membership and role-aware Gitea provisioning

New users are now added to the SilverLABS Mattermost team after account
creation. Gitea provisioning is skipped for Testers (only Developers get
repo access). Role is parsed from ticket description and threaded through
the entire approval/confirmation flow. Gitea API token is now configured.
