restore as a page (#87)

* feat: add custom restore target directory

only the original path. Closes #12.

Changes:
- Add target parameter to restore API endpoint
- Add directory picker UI in file browser restore dialog
- Add target input field in snapshot restore form
- Create reusable PathSelector component

Note: Run `bun run gen:api-client` after merging to regenerate types.

* refactor: unify restore snapshot dialogs

* refactor: restore snapshot as a page

* chore: fix liniting issues

* chore(create-notification): remove un-used prop
