Editable OAuth proxy servers configs and static platform tools

This release makes OAuth proxy server configurations editable after creation and adds static platform tools to tool discovery, including a built-in MCP logs server.

Features

• Editable OAuth proxy server configuration #2122  - Admins can now edit an existing OAuth proxy server’s audience, authorization endpoint, token endpoint, scopes, token endpoint auth methods, and environment slug without unlinking and recreating the configuration. The new POST /rpc/toolsets.updateOAuthProxyServer endpoint accepts partial updates with PATCH semantics. The dashboard’s OAuth proxy details modal exposes an Edit button that opens the OAuth modal pre-filled with the current values. Slug and provider type remain immutable after creation, and Gram-managed OAuth proxy servers stay view-only. (Author: @simplesagar )
• Static platform tools and built-in MCP logs server #2094  - Added static platform tools to tool discovery along with a built-in MCP logs server, so platform-native capabilities surface alongside user-defined tools. (Author: @danielkov )
