feat(auth): add WorkOS authentication system (#27)

* feat(schema): add auth, people, and financial tables

Add users, organizations, teams, groups, and project
members tables. Extend customers/vendors with netsuite
fields. Add netsuite schema for invoices, bills,
payments, and credit memos. Include all migrations,
seeds, new UI primitives, and config updates.

* feat(auth): add WorkOS authentication system

Add login, signup, password reset, email verification,
and invitation flows via WorkOS AuthKit. Includes auth
middleware, permission helpers, dev mode fallbacks,
and auth page components.

* ci: retrigger build

+# Authentication System Implementation
+
+## Overview
+
+Custom authentication system integrated with WorkOS API, replacing hosted UI with mobile-first custom pages that match Compass design language.
+
+## Implemented Features
+
+### Phase 1: Foundation ✅
+- WorkOS client wrapper (`src/lib/workos-client.ts`)
+- Auth layout with centered card (`src/app/(auth)/layout.tsx`)
+- Reusable password input with visibility toggle (`src/components/auth/password-input.tsx`)
+
+### Phase 2: Login Flow ✅
+- Login API endpoint (`src/app/api/auth/login/route.ts`)
+- Password login form (`src/components/auth/login-form.tsx`)
+- Passwordless login form with 6-digit codes (`src/components/auth/passwordless-form.tsx`)
+- Login page with tabs (`src/app/(auth)/login/page.tsx`)
+
+### Phase 3: Signup & Verification ✅
+- Signup API endpoint (`src/app/api/auth/signup/route.ts`)
+- Email verification API endpoint (`src/app/api/auth/verify-email/route.ts`)
+- Signup form with validation (`src/components/auth/signup-form.tsx`)
+- Email verification form (`src/components/auth/verify-email-form.tsx`)
+- Signup page (`src/app/(auth)/signup/page.tsx`)
+- Verification page (`src/app/(auth)/verify-email/page.tsx`)
+
+### Phase 4: Password Reset ✅
+- Password reset request API (`src/app/api/auth/password-reset/route.ts`)
+- Password reset confirmation API (`src/app/api/auth/reset-password/route.ts`)
+- Reset request form (`src/components/auth/reset-password-form.tsx`)
+- Set new password form (`src/components/auth/set-password-form.tsx`)
+- Reset password pages (`src/app/(auth)/reset-password/`)
+
+### Phase 5: Invite Acceptance ✅
+- Invite acceptance API (`src/app/api/auth/accept-invite/route.ts`)
+- Invite form (`src/components/auth/invite-form.tsx`)
+- Invite page (`src/app/(auth)/invite/[token]/page.tsx`)
+
+### Phase 6: Middleware & Polish ✅
+- Route protection middleware (`src/middleware.ts`)
+- Security headers (X-Frame-Options, X-Content-Type-Options, HSTS)
+- Helper functions in `src/lib/auth.ts` (requireAuth, requireEmailVerified)
+- OAuth callback route (`src/app/api/auth/callback/route.ts`)
+- Updated wrangler.jsonc with WORKOS_REDIRECT_URI
+
+## Dev Mode Functionality
+
+All authentication flows work in development mode without WorkOS credentials:
+- Login redirects to dashboard immediately
+- Signup creates mock users
+- Protected routes are accessible
+- All forms validate correctly
+
+## Production Deployment Checklist
+
+### 1. WorkOS Configuration
+Set these secrets via `wrangler secret put`:
+
+```bash
+wrangler secret put WORKOS_API_KEY
+# Enter: sk_live_...
+
+wrangler secret put WORKOS_CLIENT_ID
+# Enter: client_...
+
+wrangler secret put WORKOS_COOKIE_PASSWORD
+# Enter: [32+ character random string]
+```
+
+Generate cookie password:
+```bash
+node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"
+```
+
+### 2. Environment Variables
+Already configured in `wrangler.jsonc`:
+- `WORKOS_REDIRECT_URI: https://compass.openrangeconstruction.ltd/api/auth/callback`
+
+### 3. WorkOS Dashboard Setup
+1. Go to https://dashboard.workos.com
+2. Create a new organization (or use existing)
+3. Configure redirect URI: `https://compass.openrangeconstruction.ltd/api/auth/callback`
+4. Enable authentication methods:
+   - Email/Password
+   - Magic Auth (passwordless codes)
+5. Copy Client ID and API Key
+
+### 4. Cloudflare Rate Limiting
+Configure rate limiting rules in Cloudflare dashboard:
+- `/api/auth/login`: 5 attempts per 15 minutes per IP
+- `/api/auth/signup`: 3 attempts per hour per IP
+- `/api/auth/password-reset`: 3 attempts per hour per IP
+
+### 5. Test Production Auth Flow
+1. Deploy to production: `bun run deploy`
+2. Navigate to login page
+3. Test password login
+4. Test passwordless login
+5. Test signup flow
+6. Test email verification
+7. Test password reset
+8. Verify protected routes redirect to login
+
+### 6. Invite Users
+Use existing People page to invite users:
+1. Go to `/dashboard/people`
+2. Click "Invite User"
+3. User receives WorkOS invitation email
+4. User accepts via `/invite/[token]` page
+
+## Security Features
+
+- HTTPS-only (enforced via Cloudflare)
+- CSRF protection (Next.js built-in + WorkOS)
+- Rate limiting (via Cloudflare rules - needs setup)
+- Password strength validation (8+ chars, uppercase, lowercase, number)
+- Code expiration (10 minutes for magic auth)
+- Session rotation (WorkOS handles refresh tokens)
+- Secure headers (X-Frame-Options, HSTS, nosniff)
+- Email verification enforcement (via middleware)
+- Cookie encryption (AES-GCM via WORKOS_COOKIE_PASSWORD)
+
+## Mobile Optimizations
+
+- 44px touch targets for primary actions
+- 16px input text (prevents iOS zoom)
+- Responsive layouts (flex-col sm:flex-row)
+- Proper keyboard types (email, password, numeric)
+- Auto-submit on 6-digit code completion
+- Full-width buttons on mobile
+
+## Known Issues
+
+None currently. All lint errors have been fixed.
+
+## Next Steps (Future Enhancements)
+
+1. Add 2FA/MFA support (WorkOS supports this)
+2. Add OAuth providers (Google, Microsoft) for SSO
+3. Add audit logging for sensitive auth events
+4. Implement session timeout warnings
+5. Add "remember me" functionality
+6. Add account lockout after failed attempts
+7. Add "Login with passkey" support
