Add theme color editor and multi-step undo

- New /edit/theme-settings page with native color pickers for the
  background/primary/positive/negative theme colors plus light mode,
  contrast and saturation multipliers, custom-css-file path, and
  picker-disable. Pickers use hex; the backend converts to Glance's
  HSL "H S L" form before writing. Theme presets and full custom CSS
  intentionally still YAML.
- Numbered backup chain: save() rotates up to 10 prior versions as
  glance.yml.bak.1 .. .10 instead of a single .bak. The /edit page
  lists them with humanized timestamps and a per-row Restore button.
  Single-step "Restore previous (toggle)" is preserved.
- Restoring any backup saves the just-current state as a fresh
  .bak.1, so undo-the-undo always works.
