NNik Shevchenkofeat(admin): let the workspace owner remove any admin, superadmins included

Web Admin Dashboard

Networking: all fetches use hooks/useAuthToken.ts; never call getIdToken(), create auth headers, or read Firestore in the client. Server routes call verifyAdmin(request) from lib/auth.ts.
Revenue metrics: subscription metrics use lib/stripe-subscriptions.ts; never list subscriptions by price ID.
Admin removal: adminData/{uid}.owner === true marks the workspace owner; only the owner can DELETE /api/omi/team-members (any role, never themselves). Set the flag in Firestore, never through the UI.

Fetcher, SWR, partial-failure, and subscription-scope detail: docs/data-contracts.md.
