- Add amber (Draft Copy) and cyan (Quick Board) accent color tokens to Settings
- Create TemporarySessionBar widget: full-width colored bar between header and
  map showing session state, description, and contextual action buttons
  (Save to Original / Save as New / Save Board / Discard)
- Redesign StrategyQuickSwitcher: show original name with glowing colored dot
  indicator and tinted border in temp mode; replace 'Temporary Copy' button
  with clearer 'Draft Copy' button with pen icon and amber hover state;
  remove ambiguous 'Finish' button (actions now in session bar)
- Redesign temporary session dialogs with Lucide icons, color-coded action
  buttons, and clearer copy (e.g. 'Save Draft Changes?' with pen icon)
- Fix Quick Board double-load bug: navigateWithLoading was re-calling
  loadFromHive with default saved sessionKind, overwriting the quickBoard
  state set by createQuickBoard; added skipLoad parameter
- Update Quick Board button in folder navigator with cyan zap icon
- Remove unused strategy_provider import from strategy_save_icon_button
