fix(ui): comprehensive dark-theme hardcoded color pass

Phase 1 — globals.css: add ~45 new dark-mode override rules covering 250+
component instances at once:
- bg-*-50 (red/green/blue/yellow/amber/purple/indigo/orange/brand/emerald)
- border-*-200 (colored alert/badge borders)
- hover:bg-*-50/100 (colored hover states)
- text-amber-700/orange-600/green-600/emerald-700/brand-700 (missing overrides)
- divide-gray-50 (ChargeabilityWidget sticky section dividers)

Phase 2 — targeted component fixes:
- Button.tsx: add dark variants to secondary (bg-gray-800) and ghost variants
- DynamicFieldEditor.tsx: add dark variants to INPUT_NORMAL and INPUT_ERROR constants
- WidgetContainer.tsx: replace slate-900 (blue-tinted) gradient with neutral
  surface-card values (rgb 22,23,26 / 16,17,19)
- status-styles.ts: add explicit dark variants to PROJECT_STATUS_BADGE and
  ORDER_TYPE_BADGE (consistent with other badge maps in same file)

Phase 3 — dashboard widget tables:
- TopValueWidget: dark thead, tbody divider, row hover
- DemandWidget: dark thead, tbody divider, row hover
- ChargeabilityWidget: dark sticky h3 headers (bg-white→surface-card),
  border-gray-100 thead rows, divide-gray-50 tbodys
