fix(recipe): reimport data loss, local file support, and scroll bugs

- Add local file reimport support via _do_reimport_from_local
- Validate source_path BEFORE deleting old recipe (prevent data loss)
- Move delete_recipe after save_recipe (safe ordering)
- Preserve folder location, NSFW level, and carry over user edits
- Remove old timestamp preservation (use current time)
- Add scrollTop reset in resetAndReloadWithVirtualScroll
- Only reload on successful bulk reimport (avoid empty grid)
- Disable preserveScroll for both single and bulk reimport
