v0.11.9 UI Polish Fixes for backup section

- Fix 1: margin-bottom 1rem→1.5rem on .deploy-cross-drive
- Fix 2: info tooltip on "Módszer"; rename restic to "Titkosított mentés"
- Fix 3: replace disabled checkbox with green/gray dot status indicator
- Fix 4: progressive disclosure — dest/method/schedule selects disabled
  until "Engedélyezve" checked; backend preserves config when disabling
- Fix 5: remove all emoji from deploy.html and backups.html backup sections
