fix: use dynamic URLs for cron jobs to prevent cross-env firing

Non-prod cron jobs were hardcoding production URLs, causing double
notifications. Adds get_supabase_edge_function_url() helper that
resolves from app_config.supabase_url per environment. Also adds
text_answer question type to pack generation docs.
