fix: CMO walkthrough P1 fixes — verdict_text, per-row glyphs, conditional disclosure, dark mode (v2.0.0-alpha.3)

P1.1: verdict_text meta field + card.php wiring
- Register verdict_text (textarea, show_in_rest) on peptide CPT
- card.php reads verdict_text meta; falls back to placeholder if empty
- Hardcoded generic placeholder no longer the default for published posts
- All 3 monographs populated with CMO-authored verdict text

P1.2: per-row glyph meta fields
- Register signal_row_1/2/3_glyph (enum: ✓|!|?|⊘|⚠, show_in_rest)
- card.php reads per-row glyph from meta instead of hardcoding by position
- Missing glyph renders nothing (not a wrong glyph)
- Semaglutide: ✓✓! | BPC-157: ✓!? | Melanotan-II: !!⚠

P1.3: conditional inline disclosure
- Register has_partner_link (boolean, default false, show_in_rest)
- single-peptide.php only renders inline disclosure when has_partner_link=true
- All 3 loaded monographs set to has_partner_link=false
- Footer disclosure unaffected (always renders)

N.1: dark mode toggle hidden
- header.php: toggle button hidden (display:none + aria-hidden)
- Dark-mode verdict colors not validated for v1; re-enable in v1.1

Meta box updated with textarea, glyph dropdowns, and partner-link checkbox.
