feat(ImmichElias): implement Elias photo browser client

- Define IMMICH_BASE_URL as http://192.168.68.110:2283 and API key, person IDs
- Photo struct with id, thumbnail_url, width, height, fileCreatedAt
- Global photos array, count, current index
- HTTP helpers using esp_http_client with x-api-key header
- fetch_person_assets() POSTs to /api/search/metadata with personIds, parses cJSON {assets:{items:[...]}}
- download_thumbnail() GETs /api/assets/{id}/thumbnail?size=thumbnail (12KB WebP) with fallback note for preview=238KB JPEG for RAM safety
- UI: toolbar, title "Elias - 10739 photos", count label, img placeholder, prev/next 60x40 bottom, info label with asset id/date/size
- FreeRTOS tasks for fetch + thumb to avoid blocking LVGL
- Proper aspect no stretch, uses lvgl_get_text_font(SMALL/DEFAULT/LARGE)
- Builds clean for esp32s3, 0 missing symbols verified via nm -D
- CMake: fix TACTILITY_SDK_PATH and cJSON inclusion via json component source
- Tested Immich API locally: metadata search returns 10739-capable, thumbnail endpoints working
