When a ModelType's custom field was renamed without sending the field ID,
the service would create a new CustomField instead of reusing the existing
one, orphaning all CustomFieldValues. Now matches by orderIndex as fallback
before name, preserving the link to existing values.

preventing the MCP SDK from auto-generating structuredContent as a
JSON array (which Claude Code rejects — expects a JSON object/record).
Also adds Accept header to test helpers and SSE response parsing.
