Kian Jones 47aedfa1a7 fix(core): convert MCP ConnectionError to LettaMCPConnectionError for proper HTTP 502 responses (#9364) ...

MCP server connection failures were raising Python's builtin ConnectionError,
which bypassed the LettaMCPConnectionError FastAPI exception handler and hit
Datadog as unhandled 500 errors. Now all MCP client classes convert
ConnectionError to LettaMCPConnectionError at the source, which the existing
exception handler returns as a user-friendly 502.
