refactor: switch from remote to local script execution

- Changed script loading from remote URL to local directory path for offline usage
- Updated REPO_URL to LOCAL_SCRIPTS path (/usr/local/share/proxmenux/scripts)
- Disabled check_updates function since it's not applicable for local version
- Added comments explaining update functionality will be handled via .deb package in future
