Fix Postman collection request bodies and add missing auth endpoints

Added missing authentication endpoints:
- POST /api/v1/auth/me/avatar (Upload Avatar)
- GET /api/v1/auth/me/avatar (Get Avatar)
- DELETE /api/v1/auth/me/avatar (Delete Avatar)
- POST /api/v1/auth/logout (Logout)

Fixed request body DTOs to match backend:
- ProductSupplier: Use 'cost' field, composite key bulk delete structure
- Appointment: Remove storeId/notes, add appointmentStatus and petIds
- Adoption: Add adoptionStatus field
- Refund: Remove amount field (only saleId and reason)
- Customer: Remove address field
- Store: Use address/phone/email (not storeAddress/storePhone)
- Inventory: Use prodId (not productId)
- Supplier: Split contact into supContactFirstName and supContactLastName

All 107 requests verified against backend controllers and DTOs.
JSON validation passed. Collection is production-ready.
