Fix: Address CodeRabbit suggestions for health endpoint

- Use context.startup_time for consistent uptime tracking
  - Prefer context.startup_time when available (matches MCP health_check tool)
  - Fallback to module-level _server_start_time during startup
- Add exc_info=True to exception logging for full stack traces
  - Follows coding guidelines for error message preservation
