Initialize runtime env vars and improve media processing

Add `set_env_var_db()` initialization to app entry points to ensure environment variables are loaded from remote database on startup. Refactor env.runtime to support ID-based filtering and APP_ENV configuration merging. Enhance post-processing with picture quality detection for improved duration matching. Fix media detection logic in vidnest with fallbacks and optional chaining. Code cleanup and formatting improvements across scraper modules.
