* fix(github): pin work-item list ordering to updated-desc so cursor pagination reaches every page

The Tasks page paginates work items with an updatedAt cursor
(updated:<oldest-item), but the underlying gh calls never pinned a sort:
'gh issue list' defaults to created-desc and '--search' defaults to
best-match. Items created long ago but updated recently therefore never
appeared on any page — page 0 (created order) skipped them and every
later page excluded them via the cursor — so the pager advertised pages
the fetch chain could never reach, clicks on them clamped to the last
real page, and cross-page ordering was scrambled.

Append sort:updated-desc to every list/search invocation so the fetch
order matches the cursor field on the first and all subsequent pages.

Verified against a live 588-issue repo: the cursor chain previously
died around page 5; it now traverses 585/588 unique issues (the
remainder is the pre-existing strict '<' boundary edge for items
sharing the cursor's exact timestamp).

Fixes #8649

* fix(github): make work-item cursor pagination lossless at updatedAt boundaries

Builds on the sort-pin fix: switch the pagination cursor from strict
'updated:<' to inclusive 'updated:<=' so items sharing the boundary row's
exact updatedAt are no longer skipped between pages (the residual 3/588 edge
in #8649).

The inclusive bound re-fetches the boundary rows, so dedupe them by repoId+id
(a bare item.id like 'issue:9' collides across repos). Extract the page
accumulation out of the 12k-line TaskPage component into a pure, unit-tested
helper (accumulateWorkItemPages) that dedupes and backfills: it accumulates
fresh rows across fetches and emits uniform pageSize pages, so deduped pages
never shrink below the size totalPages (count / effectivePageSize) assumes —
which would otherwise strand the tail items and break the no-count degraded
pager.

Also hoist the updated-desc ordering into a named WORK_ITEM_LIST_SORT_QUALIFIER
constant so the cursor's ordering contract has one home.

Tradeoff: when per-repo fetch size equals pageSize, the boundary dedupe costs
one extra fetch per page; acceptable for interactive pagination and bounded by
the gh rate-limit guard. Persisting the cursor/buffer across calls is a
possible follow-up.
