- incomingQuery: staleTime:0 + refetchOnMount:'always' so pending
requests are always fresh when components mount (was inheriting
5-min global staleTime, causing empty pendingRequestIds on nav)
- NotificationsPage: show Accept button while incoming data loads
(was hidden during async gap); disable with spinner until ready
- Both toast and page: treat 409 as success ("already accepted")
instead of showing error (fixes race when both fire respond)
