Fix network connection timeouts and security detection

- Fixed detectSecurity() where WPA2 (0x100/PSK) and WPA3 (0x400/SAE)
  flags were swapped, causing NM to reject connections silently
- Added missing AP path to AddAndActivateConnection call
- Added critical connection settings: UUID, interface-name,
  autoconnect, permissions
- Changed init() to fail fast with logger.Fatal instead of
  silent failure on NM connection error
- Added auth-alg and psk-flags to WPA/WPA2 security settings
