feat: Gitea file tree visible in sidebar on ALL pages

- base.html Alpine: added giteaWorkspace, giteaOwner, giteaRepo data
- loadGiteaTree() fetches /api/gitea/.../tree and renders in sidebar
- board._sidebar_data returns gitea_owner/gitea_repo
- dashboard._sidebar_data returns gitea_owner/gitea_repo
- alpine:initialized triggers loadGiteaTree on every page load
