feat(estimate): redesign estimate builder UI and fix theme conflicts
- Restructure section/group/item hierarchy to match reference designs:
collapse chevron, cost + green price box, ellipsis menu per section;
trash on hover + cost/price per group; inline trash, orange qty=0
border, read-only cost/unit, SRS warning rows per item
- Add compact horizontal margin slider with orange accent
- Add section total banner with white/30 bordered price box
- Rewrite MaterialDetailsModal to match reference (3-row formula layout:
Measurement @ Waste = Qty, Cost/Unit with conversion note, Total formula)
- Fix MaterialDetailsModal always rendering in light mode: add dark: variants
- Fix MeasurementsModal always rendering in light mode: add dark: variants
- Fix Financial Summary sidebar always rendering in dark mode: base bg-white
with dark: gradient, all inner elements get proper dark: variants
- Add new estimate component files: MaterialDetailsModal, MeasurementsModal,
ImageUploadModal, InitialChoiceModal, TemplateSelectionModal
