Fix unreliable SSE event stream updates during workflow form transitions (#20242)

Before - workflow run not up to date, needs refresh to see created
company in some cases

## Summary
- Split `SSEQuerySubscribeEffect`'s single debounced
`updateQueryListeners` into separate `syncAdditions` (leading edge, 1s
debounce) and `syncRemovals` (trailing edge, 200ms debounce) callbacks.
This prevents query unregistrations during component mount/unmount
transitions from creating gaps where events are missed, while keeping
new registrations immediate.
- Each sync path now updates `activeQueryListenersState` granularly
(append-only for additions, filter-only for removals) instead of
overwriting the entire state, eliminating a race condition where
removals could mark unregistered queries as active.
- Mount `WorkflowRunSSESubscribeEffect` inside
`WorkflowEditActionFormFiller` so the workflow-run query subscription
stays active during form steps.
- Extract `buildSortedConnectionEdges` util that builds the resulting
edge list of a cached record connection after new records are created.
Position placeholders (`'first'` / `'last'`) bypass orderBy and are
pinned to the front/back; sortable positions (numeric or undefined) are
merged into existing edges and sorted by the connection's actual
`orderBy`. This replaces the broken `length * position` insertion logic
in `triggerCreateRecordsOptimisticEffect` that treated the sortable
`position` field as a 0-1 ratio, causing new records from SSE to land at
invisible indices in the cached list. Also fixes `totalCount` increment
for batched creates, derives `pageInfo` cursors from the final array,
and gracefully skips records whose `toReference` returns null.

## Test plan
- [x] Run a workflow with a form step — verify the workflow status
updates live after form submission (no stuck "running" state)
- [x] Run the same workflow multiple times — verify company creation
events appear live on the record index page for every run, not just the
first
- [x] Click the "+" button to create a record in first position — verify
it appears immediately at the top
- [x] Verify other SSE-backed live updates (record creation, deletion,
updates) still work correctly
