When an OpenAI/Anthropic-compatible endpoint returns a non-JSON response
(e.g. HTML error page), the SDK's paginated response parser falls back
to returning a raw string. The post-parser then calls
_set_private_attributes() on that string, causing an AttributeError.
Add explicit AttributeError handling around SDK models.list() calls in
provider check_api_key/list_llm_models_async methods, and add type
guards in convert_response_to_chat_completion to reject raw strings
before Pydantic model construction.

* fix(core): handle PermissionDeniedError in provider API key validation
Fixed OpenAI PermissionDeniedError being raised as unknown error when
validating provider API keys. The check_api_key methods in OpenAI-based
providers (OpenAI, OpenRouter, Azure, Together) now properly catch and
re-raise PermissionDeniedError as LLMPermissionDeniedError.

* fix(core): handle MCP tool schema validation errors gracefully
Catch fastmcp.exceptions.ToolError in execute_mcp_tool endpoint and
convert to LettaInvalidArgumentError (400) instead of letting it
propagate as 500 error. This is an expected user error when tool
arguments don't match the MCP tool's schema.

* fix(core): handle ExceptionGroup-wrapped ToolError in MCP executor
When MCP tools fail with validation errors (e.g., missing required parameters),
fastmcp raises ToolError exceptions that may be wrapped in ExceptionGroup by
Python's async TaskGroup. The exception handler now unwraps single-exception
groups before checking if the error should be handled gracefully.
Fixes Calendly API "organization parameter missing" errors being logged to
Datadog instead of returning friendly error messages to users.
