Christoffer Martinsson 7ad149bbe4 Replace all systemctl commands with zbus D-Bus API ...

Complete migration from systemctl subprocess calls to native D-Bus communication:

**Removed systemctl commands:**
- systemctl is-active (fallback) - use D-Bus cache from ListUnits
- systemctl show --property=LoadState,ActiveState,SubState - use D-Bus cache
- systemctl show --property=WorkingDirectory - use D-Bus Properties.Get
- systemctl show --property=MemoryCurrent - use D-Bus Properties.Get
- systemctl show nginx --property=ExecStart - use D-Bus Properties.Get

**Implementation details:**
- Added get_unit_property() helper for D-Bus property access
- Made get_nginx_site_metrics() async to support D-Bus calls
- Made get_nginx_sites_internal() async
- Made discover_nginx_sites() async
- Made get_nginx_config_from_systemd() async
- Fixed RwLock guard Send issues by using scoped locks

**Remaining external commands:**
- smartctl (disk.rs) - No Rust alternative for SMART data
- sudo du (systemd.rs) - Directory size measurement
- nginx -T (systemd.rs) - Nginx config fallback
- timeout hostname (nixos.rs) - Rare fallback only

Version bump: 0.1.197 → 0.1.198
