Watchdog: one error handler for every scenario

Every few hours the watchdog scenario checks all scenarios and assigns a shared error handler via Snowflake to those missing one.

• All scenarios checked automatically
• One error handler everywhere
• Exceptions marked and skipped
• No failure gets lost
