Add 3 passing UI tests (batch 7): insights collapse, pull-to-refresh, share no data

- TC-046: Insights section collapse/expand via header tap
- TC-047: Pull-to-refresh gesture on Insights tab
- TC-119: Share with empty data handles gracefully
- Added accessibility IDs to InsightsSectionView sections and MonthView share button
- Marked 6 tests RED: TC-040 (DEBUG triple-tap), TC-041 (dead code),
  TC-091 (DEBUG paywall lab), TC-113/114/115 (SharingListView dead code)
