fix: wire Nhắn tin button with InquiryModal on listing detail page

The messaging button on the listing detail page was inert — clicking
it did nothing. This commit completes the inquiry flow:

- Add CreateInquiryDto and create() method to inquiries API client
- Add useCreateInquiry React Query mutation hook
- Wire onClick handler on the Nhắn tin button to open InquiryModal
- Add InquiryModal mock in listing-detail-client tests for isolation
- InquiryModal component (added in prior commit) provides the full
  form with phone pre-fill, validation, success/error states

All 593 web tests pass.
