### Problem\n\nThe Proxy page uses React loading state to indicate address changes, but it has no synchronous mutation guard. Two clicks dispatched before React commits the loading state call addProxyAddress twice. Add and remove can also overlap, and their request identifiers only suppress stale UI updates; they cannot undo both backend writes.\n\n### Reproduction\n\n1. Open Studio > Proxy.\n2. Enter a valid Proxy address.\n3. Dispatch two clicks on Add before the first request resolves.\n4. Observe two addProxyAddress requests.\n\nA focused Proxy page test uses a deferred API promise and deterministically reproduces the duplicate submission.\n\n### Expected behavior\n\nAllow only one Proxy address mutation at a time and avoid starting a refresh while that mutation is pending.\n\n### Scope\n\nThe Proxy page address lifecycle and its focused component test only. -- This is an automated message from the Apache Git Service.
