feat(F-007): implement Better Auth with login and account request

Better Auth Configuration:
- Database adapter for PostgreSQL with custom schema mapping
- Email/password authentication enabled
- 7-day session expiration with 24-hour update frequency
- Custom field mappings for auth_user, auth_session, auth_account tables
- Server-side auth helpers: getSession(), requireAuth()
- Client-side React hooks: signIn, signOut, signUp, useSession

Authentication Pages:
- /login: Email/password login with error handling
- /forgot-password: Password reset request flow
- /account-request: New user registration form
  - Captures: name, email, phone, company, Epicor ID, message
  - Creates quest_account_request record for admin approval
  - Success confirmation with next steps

API Routes:
- /api/auth/[...all]: Better Auth handler for all auth operations
- /api/account-request: Account request submission endpoint

UI Components:
- Added Textarea component from shadcn/ui
- Form validation and loading states
- Toast notifications for user feedback
- Responsive card-based layouts

Session management and enhanced context (company, permissions) will be
added in F-008 middleware implementation.
