fix: relay buttons always enabled, touch sensor inversion, version bump

- MainActivity: remove isServer check — relay buttons always enabled when
  connected, regardless of device mode (fixes silently broken buttons when
  device mode accidentally set to 'client')
- client.cpp: invert HS-S43A touch sensor readings (!tActive) — sensors
  are active LOW
- build.gradle: bump versionCode 2, versionName 1.1
- platformio.ini: use stable by-id port for server ESP32
- firmware/*.bin: rebuilt with LED signaling and touch fixes
