Initial Scrypted Viewport scaffold

Plain ESP-IDF project targeting Waveshare ESP32-P4-ETH-POE with a 5" 800x480
MIPI-DSI capacitive touch panel. Stub app_main with TODOs for Ethernet, mDNS,
HTTP API (/health, /config, /frame, /sleep, /brightness), JPEG decode, and
touch callback delivery per the v1 spec in README.md.
