feat: move setup wizard to separate window (#179)

* feat: move setup wizard to separate window (MPA) with rust backend command

* fix: Remove forced GDK_SCALE exports to respect system DPI scaling

- Remove GDK_SCALE and GDK_DPI_SCALE forced exports from wrapper.sh
  These were forcing 1x scaling even on HiDPI displays with 2x scaling
- Add setup window closure handler to exit app if wizard not completed
- Fix TypeScript error with setInterval return type
- Update install.sh wrapper generation to match wrapper.sh changes

Fixes scaling issues on HiDPI displays (4K monitors with 2x scaling)

* chore: address code review comments

* chore: fix lint issues

* refactor: merge setup.html into index.html, fix race conditions and improve error handling
