feat(promo): Integrate promo code service into subscription options

Browse Source 
- Enhanced the display_subscription_options and reshow_subscription_options_callback functions to accept a promo_code_service parameter for improved discount handling.
- Updated the logic to calculate and display discounted prices based on active promo codes, including support for both regular and star-based pricing.
- Modified relevant locales to include currency symbols in discount notices for better user clarity.
