feat(FR-3075): paginate scheduling-history modals

[agatha197]

Resolves #7793 (FR-3075)

Stacked on #7650 (FR-3008). Review/merge that PR first.

Summary

The scheduling-history modals (session, deployment, route) added in #7650 fetched the entire scheduling history in a single query with no pagination arguments and fetchPolicy: 'network-only', eagerly loading every row's subSteps. For sessions/deployments/routes that went through many scheduling cycles (retries, rescheduling), this produced a large server-side aggregation and re-fetched the whole thing on every modal open — making these modals noticeably slower than the rest of the app.

This adds offset (page-number) pagination to all three modals.

Changes

• SessionSchedulingHistoryModal (self-contained useLazyLoadQuery): add $limit/$offset to the query, select count, wire useBAIPaginationOptionState with deferred limit/offset, and pass the table pagination config.
• DeploymentSchedulingHistoryModal / RouteSchedulingHistoryModal (preloaded-query pattern): add $limit/$offset + count to the query; the modal owns page state and calls the existing onReload with new limit/offset on page change. Their openers (DeploymentConfigurationSection, DeploymentReplicasTab) seed the initial loadQuery with limit: 10, offset: 0.
• Changing filter or order resets to page 1 (offset: 0).
• Uses limit + offset only — the three *ScopedSchedulingHistories are Strawberry V2 connections that reject mixed first+offset at runtime (see .claude/rules/graphql-pagination.md).

Behavior note

With pagination, the FR-3008 "expand errors only" default auto-expands non-success rows on the current page only, not across the whole history. This is the expected trade-off for paginated tables.

Verification

bash scripts/verify.sh → Relay / Lint / Format / TypeScript all pass (the Relay step only flags the regenerated __generated__ artifacts as needing commit, which are included in this PR).

Pull request overview

Adds offset (page-number) pagination to the three scheduling-history modals (session / deployment / route) to avoid fetching and rendering an entire history (including per-row subSteps) on every modal open, improving responsiveness for long-running entities.

Changes:

• Added $limit / $offset + count to the session/deployment/route scheduling-history queries and wired table pagination (total: count).
• Session modal now uses useBAIPaginationOptionState directly with deferred limit/offset in useLazyLoadQuery.
• Deployment/route modals (preloaded-query pattern) now own page state and refetch via existing onReload; openers seed initial loadQuery with { limit: 10, offset: 0 }. Filter/order changes reset to page 1.
