Ambient-credential detection for MCP now special-cases a new /api/artifacts/mcp endpoint

What

The internal helper that detects ambient credentials and OAuth needs for MCP server connections (replacing an older helper) now treats URLs under the /api/artifacts/mcp path differently from other MCP URLs. Related plumbing (artifactsMcpEntries, artifactsMcpEdgeEntries) and new OAuth scope constants for the artifacts MCP server were added, split into management, data, endpoints, and comments scopes.

Why

This lays groundwork for an artifacts-specific MCP server to be authenticated and scoped separately from other MCP connections, with finer-grained permission scopes.
