feat: implement budget utilization dynamic alert thresholds UI

[nobodieair]

Overview

This PR adds a Budget Utilization Dynamic Alert Thresholds configuration panel and live alerting UI. Operators can configure Warning and Critical percentage limits, receive immediate validation when the thresholds are invalid, and observe budget meters update in real time across all tracked department budgets. The feature uses a lightweight Zustand store, precise percentage sliders, and semantic Tailwind alert tokens for consistent light/dark contrast.

Changes

🚦 Dynamic Alert Thresholds & Live Budget Meters

• [ADD] src/stores/budget-alert-store.ts

  • Zustand store for warningThreshold, criticalThreshold, and derived active warning state.
  • Persists threshold changes and exposes validation helpers for Warning < Critical.

• [ADD] src/features/budgets/BudgetAlertSettings.tsx

  • Dual range sliders with precise percentage ticks for Warning and Critical values.
  • Inline validation message when Warning is not less than Critical.
  • Live preview gauge that reflects the current thresholds and budget utilization.

• [MODIFY] src/features/budgets/BudgetMeters.tsx

  • Budget meters now transition from green → yellow → red based on configured Warning/Critical thresholds.
  • Added real-time active warnings card listing departments at or above either threshold.

• [MODIFY] src/features/budgets/types.ts

  • Added BudgetAlertThresholds, BudgetMeterStatus, and ActiveBudgetWarning types.

• [MODIFY] src/features/budgets/mock-data.ts

  • Added department budget utilization fixtures and seeded active-warning examples.

• [MODIFY] src/styles/tokens.css

  • Added semantic success/warning/critical alert color tokens with AA/AAA-compatible contrast for light and dark themes.

Verification Results

npm run build
✅ Production build passes with no TypeScript or Tailwind errors.

Manual validation:
✅ Warning=50%, Critical=40% triggers inline validation warning
✅ Preview gauge updates immediately on every threshold change
✅ Dark-mode color-scheme contrast check passes

Acceptance Criteria	Status
Range sliders/inputs configure Warning and Critical with validation Warning < Critical	✅ Precisely ticked dual sliders plus inline validation on invalid ordering
Preview gauge shows how current budget utilization looks with set thresholds	✅ Live preview gauge re-renders on every threshold change
Card component displays real-time active warnings across all tracked department budgets	✅ Active warnings card aggregates departments exceeding Warning/Critical
Follows Tailwind styling tokens from src/styles/tokens.css for consistent alert colors	✅ All alert colors use new semantic tokens with accessible light/dark contrast

Closes #29
