Initial project: ESP32-S3 e-ink photo frame with web UI

ESP32-S3 firmware (PlatformIO) that fetches JPEGs from a photo server,
decodes on-device with PSRAM, Floyd-Steinberg dithers to the Spectra 6
6-color palette, and displays on a 7.3" GDEP073E01 e-paper panel.
Deep sleeps 1 hour between updates.

Photo server (Python/Flask) with web UI for photo management, Traefik
routing at photos.haunt.house with Google OAuth, and Home Assistant
REST sensor integration.
