fix: Restore hydration and product_refresh for store updates

- Moved hydration module back from _deprecated (needed for product_refresh)
- Restored product_refresh handler for processing stored payloads
- Restored geolocation service for findadispo/findagram
- Stubbed system routes that depend on deprecated SyncOrchestrator
- Removed crawler-sandbox route (deprecated)
- Fixed all TypeScript compilation errors
