feat: add board configuration system, refactor Config.h

Browse Source 
Board selection driven by -DTARGET_E32R35T or -DTARGET_WAVESHARE_S3_43.
Defaults to E32R35T for backward compatibility.

All hardware pin definitions moved from Config.h to board headers.
SCREEN_WIDTH/SCREEN_HEIGHT now come from board headers.
Config.h is now purely application-level configuration.

New files:
  BoardConfig.h              — board selector
  boards/board_e32r35t.h     — E32R35T pins, display, touch config
  boards/board_waveshare_s3.h — Waveshare S3 4.3" pins, display, touch config

Modified:
  Config.h — removed hardware pins section, added #include BoardConfig.h,
             added HOLD_DURATION_MS to timing section
