test: align file-preview tests with #524 and #526 (#527)

* test: align file-preview tests with #524 and #526

Two tests trailed the latest contract changes:

- test-file-handlers.js: #526 dropped structuredContent.imageData and
  carries the image base64 only in structuredContent.content. Update the
  image/SVG assertions to read content instead of the removed field.
- test-markdown-preview.js: #524 tags read_file calls with origin:'ui'.
  The Test 9 and Test 11 mocks asserted exact read_file args via
  deepStrictEqual; add origin:'ui' so the full-document reload and the
  failed-save resync paths match again.

No source changes; both were stale tests, not regressions.

* Release v0.2.43

Automated release commit with version bump from 0.2.42 to 0.2.43
