Add server, DB, and image processing modules

Introduce initial project scaffold: Express webhook server (server.js) for Immich uploads, DB pool (modules/database.js) using pg, immich repository (repositories/immichRepo.js) with get/update functions, image processing via sharp (modules/image_processor.js), a small execution helper (modules/execution_helper.js), and package.json + package-lock. Server validates a bearer token, filters non-image assets, waits briefly, compresses the image and updates DB path. Requires env vars: DB_HOST, DB_USER, DB_PORT, DB_NAME, DB_PASS, PASS_CODE, IMMICH_DATA_PATH, IMG_COMPRESSION_OUTPUT_FORMAT, IMG_COMPRESSION_OUTPUT_QUALITY, PORT.
