fix(schema): block scalars keep '#' as literal content

Inside a YAML block scalar '#' is content, not a comment; parseBlockScalar
was routing lines through stripComment/isBlank, truncating descriptions
like 'see issue #2029' and blanking comment-looking lines. Use the raw
line inside the scalar. Adds a pinning test.

- *       eligible entity pages WITH a timeline entry / eligible entity pages
- *     -> surfaced by `graph_coverage` check AND `get_health` CLI entity line.

- *     -> surfaced by `brain_score` component breakdown AND (separately) CLI.
- *
- * The two have DIFFERENT numerators/denominators. This PR labels each
- * explicitly and keeps BOTH the entity CLI line and the whole-brain line.
- *
- * Tests (no private EriadorMu data, no production/home DB, no network):
- *   - numeric denominator assertions (Metric A = 50%, Metric B = 4/15)
- *   - doctor rendered-message assertions (exact labels, no ambiguous old label)
- *   - CLI rendered-output assertions (exact lines, guard matrix)
- *   - red/green: same assertions FAIL on origin/master, PASS on this branch
