Fix unintended encoder doubleclick, Reduce long-press time

sdkconfig:
- increase encoder dead-time to fix bug where encoder triggered multiple
  short pressed events at one press.
  E.g. instantly submitted value when entering a menu page sometimes

button:
- decrease input-timeout (long press time) to 500ms same as encoder long-press
- empty encoder queue when changing to MENU

- re-enable or increase joystick scaling to have more resolution at
  slower speeds
