Bohan Jiang 6da0407b03 fix(issues): keep issue row pages in sync on observer reattach (MUL-5341) (#5978)
* fix(issues): refetch invalidated row pages on observer reattach (MUL-5341)

issueTableRowPageOptions used `refetchOnMount: false`, which blocks the
mount refetch of a *successful-but-invalidated* row page as well as an
errored one. When a row page is WS-invalidated while its dynamic
useQueries observer is detached and the observer later reattaches, the
page stays `invalidated: true / fetchStatus: idle` under the global
`staleTime: Infinity` default — the status count (facet query, always
active) updates but the list keeps a stale snapshot missing the moved
issue, until a full page refresh.

Switch to `retryOnMount: false`, which expresses the intended
"don't auto-retry an errored page" behavior without blocking stale
(invalidated) successful pages from refetching. Fresh cached pages still
don't refetch (staleTime: Infinity), so re-expanding a collapsed section
reuses settled cursor pages.

Add core regression tests for both the invalidated-refetch and the
errored-stays-errored paths, and align the status-branches test fixture
with the production client's `staleTime: Infinity`.

* fix(issues): keep errored row pages stable on reattach (MUL-5341 review)

Address Elon's review: `retryOnMount: false` alone only guards a no-data
first-load error. When a page has loaded, then an invalidation-triggered
background refetch fails, TanStack's "error" reducer flags the page
`isInvalidated: true` while retaining its data. Under the default
`refetchOnMount: true` that page is both stale and errored, so it re-fires
the failing request on every dynamic-observer reattach — bypassing the
page's explicit Retry.

Add `refetchOnMount: (query) => query.state.status !== "error"` alongside
`retryOnMount: false`: a successful-but-invalidated page still refetches on
reattach (the original bug), a fresh page stays put under
`staleTime: Infinity`, and both first-load and background-refetch errors now
wait for an explicit Retry.

Add a regression test covering the has-data background-refetch-error path
(load → invalidate → refetch fails → detach/reattach asserts no extra
request until an explicit refetch).
