fix(ogar_codebook): sync CODEBOOK mirror to OGAR class_ids::ALL (health 0x09XX)

OGAR main advanced its class_ids::ALL 32→39 (added the 0x09XX Health domain:
patient/diagnosis/lab_value/medication/treatment/visit/vital_sign) but the
contract's wire mirror CODEBOOK was still at 32 (commerce 0x0206). The
lance-graph-ogar const parity guard (mirror::CODEBOOK.len() ==
ogar_vocab::class_ids::ALL.len()) therefore failed the build of everything
that links lance-graph-ogar (symbiont, cognitive-stack).

Mirror was already prepped for health — ConceptDomain::Health, the
0x09 => Health mapping, and the 0x0901==Health test all exist; only the 7
CODEBOOK entries were missing. Added them verbatim from OGAR (stable ids).

CODEBOOK now 39 == class_ids::ALL; contract codebook tests green. Unblocks
the symbiont run-NaN census on this branch.
