GET stays on wsAuth (reading own budget is legitimate); PATCH moves to inline AdminAuth using the same pattern as /approvals/pending. No existing tests needed updating — all budget PATCH tests call the handler directly and are unaffected by router-level middleware changes.

PATCH /workspaces/:id uses ValidateAnyToken — any enrolled workspace bearer could self-clear its own spending ceiling. The dedicated AdminAuth-gated PATCH /workspaces/:id/budget is the only authorised write path. Fix 2 (MEDIUM): Strip budget_limit and monthly_spend from Get() response before c.JSON(). GET /workspaces/:id is on the open router — any caller with a valid UUID must not read billing data. Also updates four existing tests in workspace_budget_test.go that encoded the old (insecure) behaviour, and adds three new regression tests.
