Subject: [PATCH] feat(deployment): add readLogs procedure to fetch deployment
 logs

- Introduced a new `readLogs` procedure that allows users to retrieve logs for a specific deployment by providing the deployment ID and an optional tail parameter.
- Implemented permission checks to ensure users have access to the requested logs.
- Enhanced log retrieval for both cloud and non-cloud environments, utilizing appropriate commands based on the server context.
