Add a data-driven 'user' config kind so Gitea accounts are declared as
config/git.unkin.net/user/<name>.yaml, mirroring the existing repository
and team kinds. Wire the yaml into a new modules/user submodule that
creates a gitea_user (provider go-gitea/gitea 0.7.0, already pinned).
The provider's user resource requires a password; generate a per-user
random_password so nothing sensitive is hardcoded and only a placeholder
lives in state (tokens come later from vault-plugin-secrets-gitea).
Provision teabot's implementer and reviewer personality accounts with a
conservative posture: not site admins, no org creation, no repo creation,
limited profile visibility.
