Title: Add REST API endpoints and modernize UI

Description:

Overview

Is Pull Request mein humne Spring PetClinic project mein REST API endpoints add kiye hain aur UI ko modernize kiya hain.

Changes Made

1. REST API Controllers (New)

OwnerApiController (/api/owners)

• GET /api/owners - Saare owners ko paginated list mein retrieve karo
• GET /api/owners/{id} - Owner by ID fetch karo
• GET /api/owners/search?lastName=xxx - Last name se owners search karo
• POST /api/owners - Naya owner create karo
• PUT /api/owners/{id} - Existing owner update karo
• DELETE /api/owners/{id} - Owner delete karo

PetApiController (/api/pets)

• GET /api/pets - Saare pets ki paginated list
• GET /api/pets/{id} - Pet by ID fetch karo
• GET /api/pets/owner/{ownerId} - Kisi owner ke saare pets
• POST /api/pets/owner/{ownerId} - Owner ke liye naya pet create karo
• PUT /api/pets/{id} - Pet update karo
• DELETE /api/pets/{id} - Pet delete karo

VisitApiController (/api)

• GET /api/visits - Saare visits
• GET /api/pets/{petId}/visits - Kisi pet ki saari visits
• POST /api/pets/{petId}/visits - Pet ke liye naya visit create karo
• PUT /api/visits/{id} - Visit update karo
• DELETE /api/visits/{id} - Visit delete karo

2. New Repository Interfaces

• PetRepository.java - Pet entity ke liye JPA repository
• VisitRepository.java - Visit entity ke liye JPA repository

3. Entity Enhancement

• Visit.java mein ManyToOne Pet relationship add kiya - isse visits ko pets se link karna possible hua

4. UI Improvements

• Welcome Page: Modern hero section with gradient background, feature cards (Owners, Vets, Pets & Visits), aur stats section
• Navigation Bar: Gradient styling add kiya aur brand logo include kiya
• Footer: Clean modern footer with copyright
• SCSS Styles: Tables, cards, buttons, forms, alerts, pagination - sabko modern styling di

5. i18n Updates
