- Added UNIQUE KEY on companies.name in DB so ON DUPLICATE KEY UPDATE
actually fires instead of always inserting
- Removed config_json and phone_number_id from upsert: those hold
admin-configured bot data and should never be overwritten by ERP sync
- Skip placeholder API key to avoid sending a fake Bearer token
- Improved error reporting: curl errors, raw response preview, per-company
error labels
