refactor(settings): move types.ts to shared folder

- Move types.ts to shared/types.ts
- Update all section files to import from ../shared/types
- Update theme-options.ts to import from ../../shared/types
- All TypeScript diagnostics passing
- Completes settings-view folder restructuring

Final structure:
- api-keys/ (with hooks/, config/)
- appearance/ (with config/)
- cli-status/ (claude, codex)
- feature-defaults/
- keyboard-shortcuts/
- kanban-display/
- danger-zone/
- shared/ (types.ts)
