10: Upgrade dependencies p1

[camd]

Post-React 19 upgrade:

Phase 2: Replace Inactive/Problematic Dependencies - COMPLETED ✅

Completed: January 2026

Summary

1. react-highlight-words updated from 0.20.0 to 0.21.0
2. react-lazylog tested with React 19 - works correctly (react-virtualized supports React 19)
3. react-hot-keys tested with React 19 - works correctly (peer dep >=16.9.0)
4. react-table-6 deferred to Phase 4 (works at runtime despite peer dep warning)
5. react-linkify kept at 0.2.2 (1.0.0-alpha not production-ready)

2.1 react-lazylog Status

Current: 4.5.3 (INACTIVE - mozilla-frontend-infra marked as archived)
Usage: 2 files (ui/logviewer/App.jsx, ui/shared/tabs/LogviewerTab.jsx)
Status: ✅ Works with React 19

The original react-lazylog from Mozilla is no longer maintained, but its dependency react-virtualized explicitly supports React 19 (^16.3.0 || ^17.0.0 || ^18.0.0 || ^19.0.0). Build and tests pass.

Future: If issues arise, migrate to @melloware/react-logviewer.

2.2 react-table-6 Replacement (Deferred)

Current: 6.11.0 (peer dependency warning)
Usage: 5 files in ui/intermittent-failures/ and ui/perfherder/
Risk: High - Significant refactoring required

Status: Works at runtime despite peer dependency warning. Migration to TanStack Table v8 would require significant refactoring since it's headless (no built-in UI).

Recommendation: Defer to Phase 4. Document current behavior and monitor for actual issues.

2.3 react-highlight-words ✅

Updated: 0.20.0 → 0.21.0
Usage: 1 file (ui/shared/tabs/failureSummary/BugListItem.jsx)

2.4 react-linkify

Current: 0.2.2 → 1.0.0-alpha available
Usage: 2 files (ui/shared/RevisionLinkify.jsx, ui/shared/BugLinkify.jsx)

Status: Kept at 0.2.2. Alpha version is not production-ready.

2.5 react-hot-keys ✅

Current: 2.7.3
Usage: 1 file (ui/job-view/KeyboardShortcuts.jsx)
Status: Works with React 19 (peer dep >=16.9.0)
