Ho Ngoc Hai 5d4ecdeb2f feat(web): AVM v2 upgraded valuation dashboard (TEC-2763) ...

R5.4 ships the upgraded AVM UI behind the `avm_v2` A/B flag. When the
flag is on, the dashboard exposes:

- Tab switch between single valuation and multi-property compare
- Waterfall drivers chart (ValueDriversChart) alongside the existing
  horizontal bar breakdown
- Mapbox comparables map with similarity-coloured markers and an
  optional highlighted subject pin
- Confidence interval + range bar and PDF export remain available
- Valuation history chart surface unchanged (still lazy-loaded)

Flag plumbing (useAvmV2Flag):
- NEXT_PUBLIC_FEATURE_AVM_V2=1 enables by default
- `?avm_v2=1|0` URL param forces + persists to localStorage
- safe localStorage handling (no throw when storage is blocked)

Tests: comparables-map, value-drivers-chart, use-avm-v2-flag specs
added. Pre-existing "Yếu tố chính" assertion in valuation-results.spec
updated to match the current copy ("Yếu tố ảnh hưởng giá") so the
valuation suite is green (7 files, 52 tests).
