Add orchestration test suite: 17 tests for Phase 7c+7d
Tests cover page data cache, optimistic cache update/revert/confirm, offline connectivity tracking, offline queue mutation, and offline-aware routing. Registered in test runner with mocked platform functions. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
