Keep fixed market prices in sync

Create tag-based pricing rules, preview every change, verify each write, and restore previous fixed prices with exact rollback.

• Sync with verification. Keep tagged products aligned after product and base-price updates.
• Rollback safely. Restore the previous fixed amount or remove an override that did not previously exist.
