feat(background): persist viewport background across sessions (#188)

Browse source 
The BACKGROUND command set a per-tab colour that was lost on restart and
didn't apply to new drawings, so there was no way to make a non-black
background stick. Persist the chosen model/paper background in UserSettings
(settings.txt) and re-apply it on launch and to every drawing tab created
afterward.

- settings.rs: persist `bg_color` / `paper_bg_color` as 0–255 RGB triplets.
- App gains `default_bg_color` / `default_paper_bg_color`; current_settings /
  apply_settings round-trip them, and apply_settings pushes the restored
  colour onto existing tabs. New/opened/replaced tabs call `apply_bg_default`.
- BACKGROUND updates the persisted default, saved centrally via
  persist_settings_if_changed; RESET clears it.
