Add missing strings import for subscription fallback checks, log failed subscription refunds after retries, and extend sidebar module settings with a subscription management toggle plus translations.
Use POST and form parsing for epay notify/return routes, persist epay orders before provider calls with expiry on failure, and ensure notify handlers retry correctly.
Restrict subscription-first fallback to insufficient-subscription errors and log refund failures after retries to avoid silent quota drift.
Remove per-model subscription items and switch to a single total quota per plan and user subscription. Update billing, reset, and logging flows to operate on total quota, and refactor admin/user UI to configure and display total quota consistently.
Replace separate enable/disable flows with a single PATCH API that updates the enabled flag.
Update frontend hooks and table actions to call the unified endpoint and keep UI behavior consistent.
Introduce a minimal admin controller handler and route for the status update.
Add plan-level quota reset periods and display/reset cadence in admin/UI
Enforce natural reset alignment with background reset task and cleanup job
Make subscription pre-consume/refund idempotent with request-scoped records and retries
Use database time for consistent resets across multi-instance deployments
Harden payment callbacks with locking and idempotent order completion
Record subscription purchases in topup history and billing logs
Optimize subscription queries and add critical composite indexes
Apply consistent code formatting across the entire codebase using
gofmt and lint:fix tools. This ensures adherence to Go community
standards and improves code readability and maintainability.
Changes include:
- Run gofmt on all .go files to standardize formatting
- Apply lint:fix to automatically resolve linting issues
- Fix code style inconsistencies and formatting violations

Implement a new subscription-based billing model alongside existing metered/per-request billing:
Backend:
- Add subscription plan models (SubscriptionPlan, SubscriptionPlanItem, UserSubscription, etc.)
- Implement CRUD APIs for subscription plan management (admin only)
- Add user subscription queries with support for multiple active/expired subscriptions
- Integrate payment gateways (Stripe, Creem, Epay) for subscription purchases
- Implement pre-consume and post-consume billing logic for subscription quota tracking
- Add billing preference settings (subscription_first, wallet_first, etc.)
- Enhance usage logs with subscription deduction details
Frontend - Admin:
- Add subscription management page with table view and drawer-based edit form
- Match UI/UX style with existing admin pages (redemption codes, users)
- Support enabling/disabling plans, configuring payment IDs, and model quotas
- Add user subscription binding modal in user management
Frontend - Wallet:
- Add subscription plans card with current subscription status display
- Show all subscriptions (active and expired) with remaining days/usage percentage
- Display purchasable plans with pricing cards following SaaS best practices
- Extract purchase modal to separate component matching payment confirm modal style
- Add skeleton loading states with active animation
- Implement billing preference selector in card header
- Handle payment gateway availability based on admin configuration
Frontend - Usage Logs:
- Display subscription deduction details in log entries
- Show step-by-step breakdown of subscription usage (pre-consumed, delta, final, remaining)
- Add subscription deduction tag for subscription-covered requests
