V84 LinkedIn Archi score 4.8 to 8.9/10 root cause fix

ROOT CAUSE: audit_score hardcoded 4.8 (not computed) + backspace bytes in PHP regex broke posts_with_metric

FIXES:
- Composite weighted score 9 KPIs (replaces hardcoded 4.8)
- Clean regex (removes \x08 backspace bytes)
- Fallback 30d reach when no recent posts
- Enrich 18 posts tagline + honest numbers (157K HCPs, 626 tools, 153/153 NR)
- Rewrite 3 risky claims posts (6/13/15) honest language

RESULTS:
- audit_score: 4.8 -> 8.9/10 (+85 pct)
- 6/9 KPIs now at 10/10 (engagement, tagline, risky=0, parity, named_cases)
- Remaining: posts_with_metric, reach_30d, services_up, proofs_cited

NR: 153/153 CONSTANT 57 sessions
