feat: dismiss timed out jobs

[quitrk]

• do not re-process timed out jobs, just marked them with error status
• avoid restarting the whole process on job timeout, but rather restart just the openai api server
• add a redis collection for storing jobs keys that errored out
• add metrics for number of error jobs and number of restarts
• fix broken unit test for OpenAI execution
• disable retries for local llm execution
