Add live capture visuals: progress bar, blinking active targets, per-network state

- Progress bar under status line shows captured/total WPA targets
- Three visual states per network:
  Green (pending) -> Orange blinking (active target) -> Red + checkmark (captured)
- Active targets show live info: client count during observation,
  EAPOL progress during capture (e.g. "⚡ NetworkName 1/2")
- Status line shows channel number and phase context
- LVGL symbols: lightning bolt for active, checkmark for captured
- Title updated to "⚡ Capture" with WiFi icon
