Major Enhancement: NestJS Migration + CASL Authorization + Error Handling

Complete rewrite from Express to NestJS with enterprise-grade features: ## Backend Improvements - Migrated from Express to NestJS 11.0.1 with TypeScript - Implemented Prisma ORM 7.3.0 for type-safe database access - Added CASL authorization system replacing role-based guards - Created global exception filters with structured logging - Implemented Auth0 JWT authentication with Passport.js - Added vehicle management with conflict detection - Enhanced event scheduling with driver/vehicle assignment - Comprehensive error handling and logging ## Frontend Improvements - Upgraded to React 19.2.0 with Vite 7.2.4 - Implemented CASL-based permission system - Added AbilityContext for declarative permissions - Created ErrorHandler utility for consistent error messages - Enhanced API client with request/response logging - Added War Room (Command Center) dashboard - Created VIP Schedule view with complete itineraries - Implemented Vehicle Management UI - Added mock data generators for testing (288 events across 20 VIPs) ## New Features - Vehicle fleet management (types, capacity, status tracking) - Complete 3-day Jamboree schedule generation - Individual VIP schedule pages with PDF export (planned) - Real-time War Room dashboard with auto-refresh - Permission-based navigation filtering - First user auto-approval as administrator ## Documentation - Created CASL_AUTHORIZATION.md (comprehensive guide) - Created ERROR_HANDLING.md (error handling patterns) - Updated CLAUDE.md with new architecture - Added migration guides and best practices ## Technical Debt Resolved - Removed custom authentication in favor of Auth0 - Replaced role checks with CASL abilities - Standardized error responses across API - Implemented proper TypeScript typing - Added comprehensive logging Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

-- Migration: Add user management fields
-- Purpose: Support comprehensive user onboarding and approval system
-
-- 1. Add new columns to users table

-ADD COLUMN IF NOT EXISTS status VARCHAR(20) DEFAULT 'pending' 
-  CHECK (status IN ('pending', 'active', 'deactivated')),
-ADD COLUMN IF NOT EXISTS phone VARCHAR(50),

-ADD COLUMN IF NOT EXISTS rejected_at TIMESTAMP,
-ADD COLUMN IF NOT EXISTS deactivated_by VARCHAR(255),
-ADD COLUMN IF NOT EXISTS deactivated_at TIMESTAMP;
-
-- 2. Update existing users to have 'active' status if they were already approved
-UPDATE users 
-SET status = 'active' 
-WHERE approval_status = 'approved' AND status IS NULL;
-
-- 3. Update role check constraint to include 'viewer' role
-ALTER TABLE users 
-DROP CONSTRAINT IF EXISTS users_role_check;
-
-ALTER TABLE users 
-ADD CONSTRAINT users_role_check 
-CHECK (role IN ('driver', 'coordinator', 'administrator', 'viewer'));

-CREATE INDEX IF NOT EXISTS idx_users_email_status ON users(email, status);
