Refactor AlmaLinux VM installer & lobehub setup

Modernize and simplify VM installer and lobehub installation flows.

Key changes:
- install/lobehub-install.sh: consolidated apt invocation, replaced manual ParadeDB .deb download with fetch_and_deploy_gh_release helper, added postgresql pg_search preload configuration and restart, moved pnpm installation into setup_nodejs via NODE_MODULE, and adjusted build env handling.
- vm/almalinux-10-vm.sh: major refactor to source shared functions from COMMUNITY_SCRIPTS_URL, add load_functions, centralize cloud-init handling (configure_cloudinit_ssh_keys / setup_cloud_init), replace many custom UI/helper functions with standardized helpers and exit_script, update traps and error handling, simplify prompts/defaults, use $STD for apt operations, and streamline image customization and VM creation flow.
- Added vm/headers/almalinux-10-vm containing the VM header art and title.

These changes centralize common logic, improve cloud-init integration, reduce duplicated code, and make maintenance easier.
