v0.4.6: MariaDB validation fix + dashboard deployed-only + protected stack restart

- Fix ValidateDump() to scan first 10 lines for header (MariaDB 11.4+ sandbox comment)
- Dashboard shows only deployed/protected stacks, heading "Telepített alkalmazások"
- Protected stacks show restart button when operational (both dashboard + stacks page)
- API blocks all actions except restart on protected stacks
- docker-setup.sh creates .felhom.yml for FileBrowser (subdomain: files)
