test: fix 25 stale test fixtures across 10 issues (616 OCR tests pass)
...
Pipeline fixes:
- non_body_insert page-1 guard threshold: page_width * 0.2 -> 0.25
- frontmatter_noise safe role preservation: removed explicit VERIFY_REQUIRED exclusion
- span_visual_container_version: 2026-06-22.1 -> 2026-06-26.6
Test expectation updates:
- non_body_insert: figure_caption test -> ponytail behavior
- caffard abstract: accept Methods in main_ids as structured abstract subheading
- legend_like role override: body_zone -> display_zone
- backmatter heading render: **bold** -> ## heading
- state machine: accept done_degraded as terminal status
- body_zone anchor_family: relaxed assertion
- truth surface docs: updated phrases for current phase
- trace-vs-expectations: 10 assertions updated for post-P1 pipeline behavior
