feat(webui,recon): drop PineAP mode card, sort recon report APs by signal

- Remove the Passive/Active/Advanced mode card from the PineAP dashboard
  and move the RF Role (radio1) card into its slot, along with the now
  dead mode state machinery and mode-card-only CSS.
- Sort recon HTML report access points by signal strength (strongest first).
