Subject: feat: web-based WiFi setup via captive portal, portrait-only display

- Remove touchscreen WiFi setup (touch.c, keyboard.c, wifi_setup.c from build)
- Remove offscreen buffer and landscape rotation from axs15231b driver
- Add /setup HTML page with WiFi scan/connect via captive portal
- Add /wifi/scan, /wifi/connect, /wifi/status HTTP endpoints
- Display shows SETUP_PENDING (QR + SSID + setup URL) when unconfigured
- Display shows ERROR with setup URL when upstream is down
- All 101 unit tests pass, builds and flashes to Board C
