Fix WiFi connect: add polkit rule for NetworkManager + hostname in /etc/hosts 

The Flask service runs as user 'pi' in a non-interactive session.
nmcli device wifi connect requires polkit authorization which was missing,
causing 'Not authorized to control networking' errors.

- config/50-babycam-network.rules: grants pi full NetworkManager access via polkit
- setup.sh: installs polkit rule, restarts polkit, fixes /etc/hosts hostname entry
  (missing 127.0.1.1 entry caused harmless but annoying sudo warnings)
