Add Baserow, LabCA, and LobeHub installers

Add container templates, install scripts, and metadata for Baserow, LabCA, and LobeHub. New ct/*.sh scripts provide container build and update logic (fetching GitHub releases, backup/restore, build steps). New install/*.sh scripts install dependencies, configure PostgreSQL/Node/uv/PNPM as needed, run migrations, and create systemd services for each app. Corresponding json/*.json entries add metadata (ports, resource defaults, docs, and notes) for UI/registry integration.
