- Fix raw string literal escaping in mcid.rs and ocr_regions.rs tests
- Update serve.rs tests for http_body_util and tower APIs
- Update verification note to reflect indent trigger fix

All changes are test infrastructure related to Phase 4.4 Block Formation.

 2. **Indented first line of paragraph: NOT split unconditionally** ✅
    - Verified in pdftract-fy89c acceptance criteria
-   - Test `test_indented_first_line_new_block`: indent > 0.03 * column_width creates new block
-   - This is correct behavior per plan (line 1696)
+   - Test `test_indented_first_line_of_paragraph_not_split`: drop-cap style (first line indented, rest flush) stays together
+   - Commit `d0f52751`: fix indent trigger to not split drop-cap paragraphs
+   - Indent trigger only fires when current line x0 > block avg x0 (not on first line)
