Enhance promo code management and add bulk creation functionality

- Refactored the promo code creation process into a step-by-step flow, improving user guidance and validation.
- Introduced bulk promo code creation with a structured multi-step process, allowing admins to create multiple codes efficiently.
- Added new states for managing the promo code creation process and bulk operations.
- Implemented panel statistics retrieval to provide admins with insights into system performance and user activity.
- Updated localization files to support new messages and prompts related to promo code management and statistics.
