PR-1 of the architecture review fixes.
Two entry-level filters before figure matching:
1. _is_table_owned_media(): excludes media_asset blocks with table
roles/raw_labels/hints from the figure asset pool. Previously these
entered as figure candidates and ended up as unmatched legends/orphans.
2. _looks_like_inline_figure_body_reference(): detects body text like
'Figure 11-10 shows...' (hyphenated ranges, list ranges) and flags
it as an inline reference, not a figure legend. Applied in both
ocr_figures.py and ocr_roles.py for consistent early rejection.
Verified on real vault:
SKXTCE6M: unmatched_legends 6→0, overall yellow→green
SRNJDAA2: unmatched_legends 9→0
Tests: 384 pass (+9 new), 0 fail
