feat(platform): add typed platform api client

[jordienr]

Problem

The MCP only has generated types and a client for the legacy Management API. Newer Platform API endpoints cannot be called safely without hand-written request and response types.

Fix

Generate a separate Platform API schema and add a typed client alongside the existing Management API client. Extend the type-generation workflows to keep both schemas synchronized.

How to test

• Run pnpm --filter @supabase/mcp-server-supabase test -- --run src/platform-api/index.test.ts
• Expected result: the Platform API client uses the resolved endpoint URL with Bearer authentication and caller-provided headers.
• Run pnpm --filter @supabase/mcp-server-supabase generate:platform-api-types
• Expected result: regeneration produces no diff.

Just confirming if this is still needed, since there's talk of moving the motivating health advisors endpoint to management API? As you mention, IIRC MCP doesn't have access to platform endpoints.
