fix: SearXNG printf command + edit site modal

SearXNG:
- Use proper command list format instead of shell string
- Use printf with \n for proper newlines in limiter.toml
- Use exec to properly start the entrypoint

Edit Site Modal:
- Add Dialog component import
- Add siteModalOpen and editSiteData state
- Create proper modal with form for editing sites
- Modal opens when clicking edit button
- All site fields editable in modal
