Move common type aliases, peripheral bundles, and init helpers for ESP32-S3 boards into src/board/esp32s3.rs. Heltec V3 (146->48 lines) and V4 (155->57 lines) become thin wrappers containing only board-specific code (Vext GPIO pin, display reset sequence). Update build.rs to exclude esp32s3.rs from board discovery and mod.rs.j2 to include the shared module under an ESP feature gate.
