feat: Complete form accessibility enhancement (WCAG 2.1 AA)

Implemented comprehensive form accessibility improvements across all critical forms:

**Accessibility Attributes Added:**
- aria-required="true" on all required form fields
- aria-invalid on fields with validation errors
- aria-describedby linking error messages to inputs
- Unique id attributes on FormHelperText for error association
- role="alert" on error messages for screen reader announcements
- labelId on Select components for proper label association
- noValidate on forms to use custom validation

**Forms Updated:**
1. Login Form (app/(auth)/login/page.tsx)
   - Email and password fields with full ARIA support
   - Error message association with aria-describedby

2. Registration Form (app/(auth)/register/page.tsx)
   - All text fields: name, email, password, DOB, parental email
   - Checkbox fields: Terms, Privacy, COPPA consent
   - Conditional required fields for minors

3. Child Dialog (components/children/ChildDialog.tsx)
   - Name, birthdate, gender fields
   - Dynamic aria-invalid based on validation state

4. Tracking Forms:
   - Feeding form (app/track/feeding/page.tsx)
     - Child selector, side selector, bottle type
     - Food description with required validation
   - Sleep form (app/track/sleep/page.tsx)
     - Child selector, start/end time fields
     - Quality and location selectors

**WCAG 2.1 Compliance:**
- ✅ 3.3.2 Labels or Instructions (AA)
- ✅ 4.1.3 Status Messages (AA)
- ✅ 1.3.1 Info and Relationships (A)
- ✅ 3.3.1 Error Identification (A)

**Documentation:**
- Updated REMAINING_FEATURES.md
- Marked Form Accessibility Enhancement as complete
- Status: 79 features completed (57%)
