Move web templates and static assets to web/ dir alongside binary; update install.sh to deploy them

- Moved templates from src/web/templates/ to web/templates/ and
  static CSS from src/web/static/ to web/static/
- Updated handlers.go paths (src/web/ → web/) so the binary looks
  for templates at the correct deployment location
- Updated install.sh to create web/templates/ and web/static/
  directories and download the files from the repo
- Removed old src/web/ directory (dead code)
- Rebuilt inboxer binary with corrected template paths
