Improve form validation and accessibility

[kumudasrip]

Closes #41

• Summary: Add consistent client-side validation, accessible per-field error messages, ARIA attributes, and visual error highlights for public and admin/profile forms. This improves UX, prevents invalid submissions client-side, and keeps server-side flows unchanged.
• Changes:
  • Validation & Accessibility: Added fieldErrors/errors handling, aria-invalid/aria-describedby, and inline error elements.
  • Relaxed Login rule: softened overly-strict password regex to a minimum-length rule to avoid blocking existing users.
• Files touched:
  • src/components/customer/ReservationsSection.jsx
  • src/pages/public/Login.jsx
  • src/components/admin/upi/UPIFormModal.jsx
  • src/components/admin/menu/menuCard/CategoryFormModal.jsx
  • src/components/admin/menu/menuCard/FoodItemFormModal.jsx
  • src/components/admin/store/tables/TableFormModal.jsx
  • src/components/admin/store/branch/BranchFormModal.jsx
  • src/components/admin/profile/profileComponents/PersonalInfoCard.jsx
  • src/components/admin/profile/profileComponents/SecurityCard.jsx
• Testing:
  • Ran development server and exercised these forms to verify: inline errors appear, inputs get visual red border when invalid, ARIA attributes link to error text, and valid submissions still call the same API endpoints.
  • Quick commands:

npm install
npm run dev
# Open app and test Reservatons, Login, UPI, Category, Menu Item, Branch, Table, and Profile forms

Hello @rdodiya ,

Just following up on this PR. Since it affects several commonly used form components and there are currently no merge conflicts, an early review/merge would be very helpful. It would make the validation and accessibility improvements available for future contributions and help avoid potential conflicts as development continues.

Thank you for your time and consideration. Looking forward to your review!
