Refactor project into two standalone components

Split monorepo into separate units for future independent repositories:
- media-server/: Standalone FastAPI server with own README, requirements,
  config example, and CLAUDE.md
- haos-integration/: HACS-ready Home Assistant integration with hacs.json,
  own README, and CLAUDE.md

Both components now have their own .gitignore files and can be easily
extracted into separate repositories.

Also adds custom icon support for scripts configuration.
