🗂️ refactor: implement Phase 2 folder-pattern compliance

- Move dialogs to src/components/dialogs/ folder:
  - delete-session-dialog.tsx
  - delete-all-archived-sessions-dialog.tsx
  - new-project-modal.tsx
  - workspace-picker-modal.tsx
- Update all imports to reference new dialog locations
- Create barrel export (index.ts) for board-view/components/kanban-card/
- Create barrel exports (index.ts) for all 11 settings-view subfolders:
  - api-keys/, api-keys/hooks/, appearance/, audio/, cli-status/
  - components/, config/, danger-zone/, feature-defaults/
  - keyboard-shortcuts/, shared/

This is Phase 2 of folder-pattern.md compliance: organizing dialogs
and establishing consistent barrel export patterns across all view subfolders.
