feat: add options for bypassing cache in session and subagent detail retrieval

- Updated handleGetSessionDetail and handleGetSubagentDetail functions to accept an optional options parameter for bypassing cache.
- Modified IPC and API methods to support the new options parameter, enhancing flexibility in data retrieval.
- Adjusted MemberLogsTab to utilize the bypassCache option when fetching log details, improving data freshness.
