fix(workflows): #53 dev-cycle correctness (protection-independent)

- cleanup.yml: preserve dev/rc/release-line + version/* branches (skip-list was
  deleting version/* release-history branches every week)
- notify.yml: point workflow_run at the real workflow names (Universal: Build &
  Release / Joomla: Extension CI / Generic: Project CI) so release/failure ntfy
  actually fires
- ci-joomla.yml: add plain `dev` to PR triggers so Joomla CI runs on feature->dev
- pr-check.yml (Joomla): detect platform via the MokoGitea metadata API instead
  of the removed .mokogitea/manifest.xml (Joomla PR gates were silently skipping)

Refs Template-Generic#53. Dev-sync/version-bump fixes deferred until the
branch-protection provisioner rolls out (mcp-mokogitea-api#30).
