feat(ui): apply inquiry list and modal design

Apply the supplied inquiry layout to the list and native write/detail dialogs while preserving existing API requests, author controls, attachments, comments and search. Keep legacy entry links and confirm before discarding drafts.

Validation: 98 tests and syntax checks pass; mocked Chromium desktop/mobile and six author/session visibility scenarios pass.
