Add verbose debug logging across services and cron jobs

Add createLogger to tmdb client, image-cache, availability, and
webhooks services. Replace all silent .catch(() => {}) in metadata.ts
with debug-level error logging. Add progress and success logs in cron
job bodies, colors extraction, and webhook processing. Fix pre-existing
unused parameter lint warning in title-card.tsx.
