fix(mobile): keep session lists loading until the query settles

[iscekic]

Changelog for users

• Session lists no longer flash an empty message on a cold open.
• The sessions page shows loading skeletons until the session request settles.
• The history screen shows "No past sessions" only after loading finishes with an empty list.
• The device sessions screen shows "No active sessions" only after its request settles.
• Cached session rows stay visible during a background refresh or refocus.
• A load error still appears only after loading settles.
• A search or filter with no matches keeps its own empty state.

Changelog for maintainers

• apps/mobile/src/components/agents/session-list-loading.ts adds selectSessionListIsLoading, which decides loading from React Query v5 isPending rather than isFetching; isLoading is false on the first render and while a query is paused.
• apps/mobile/src/components/agents/session-history-screen.tsx calls the selector; the previous storedIsFetching && storedLoadedPageCount === 0 check is removed.
• apps/mobile/src/lib/hooks/use-agent-sessions.ts exposes storedIsPending, and use-agent-session-list-data.ts forwards it. A cached page makes isPending false, so a refetch keeps rows.
• apps/mobile/src/lib/device-sessions.ts classifies on isPending, and device-sessions-screen.tsx passes the query's isPending instead of isLoading.
• Regression coverage: apps/mobile/src/components/agents/session-list-loading.test.ts covers the first render, cached rows, settled empty, search, and error ordering; the mounted history and device-sessions tests were updated.
• Check first: session-list-content-surface.ts still gates the empty and error surfaces on isLoading, so the loading selector is the one changed input to that decision.
• Risk: isPending stays true for a paused or offline query by design, so those surfaces keep skeletons until the request settles.

Owner request

Fix the empty state that flashes on the sessions page before the list loads.

Surface: mobile-app.

Symptom:
On a cold open of the sessions page, the empty state paints for a moment before the loading state or the session rows appear.
The empty state is "No past sessions" or another body-empty message.

Expected:
On a cold open, show the loading skeletons until the request settles.
Show the empty state only after loading completes and the list is truly empty.

Reproduce this on the sessions page before you change product code.
Find and fix the shared cause across the session list surfaces, including the history screen.
Keep the current rules:

• Cached session rows must never blank out during a background refetch.
• A load error must show the error surface only after loading settles.
• A search or filter with no matches must keep its own empty state.

Verification:

• Add focused regression checks for the loading and empty-state decision, including the first render before the request settles.
• Prove the cold open on a device: the loading state shows first and the empty state does not flash.
• Prove the true empty case still shows the empty state after loading settles.
• Put the recording, or screenshots if a recording is unavailable, in the pull request (PR) body.

Constraints:

• Do not commit fixtures, E2E-only code, test hooks, or test-only runtime flags.
• Keep temporary test support outside the product diff.
• Do not leave follow-ups.
• Let the workflow open and maintain the PR.
• Finish only after current-head continuous integration (CI) is green and Kilobot recommends Merge.

[e1] Cold open the Sessions history screen (Agents tab -> See all): loading skeletons render first and 'No past sessions' never flashes before the request settles. — android (emulator-5554).

Open findings the workflow could not fix

• the verify loop is past its round ceiling (round 30) and HEAD 4919192 has not moved since round 28: the checks keep failing without a landed fix.

The loading/empty-state logic change itself is sound: keying the cold-open decision off React Query v5 isPending (rather than isLoading/isFetching) correctly keeps skeletons until the query settles while cached pages keep isPending false, so background refetches do not blank the list. Verified on HEAD 856fb8121b6653405a511468ed57c07f96000799.
