feat: billing system — service plans, wallet, cost calculation
- Backend: billing module with ServicePlan, PricingRule, Wallet, WalletTransaction entities - Admin can CRUD service plans with hourly/monthly/yearly billing cycles - Each plan has flexible pricing rules (base_fee, cpu, memory, storage, db addon) - Wallet system: auto-created per user, charge, deduct, refund, transaction history - Cost calculation endpoint: cross-cycle conversion (hourly*720=monthly, monthly*12=yearly) - Frontend: admin billing management page (/dashboard/admin/billing) - Frontend: user wallet page with balance, quick-charge, transaction history - Deploy page: cost breakdown shown in Review step (hourly/monthly/yearly) - Navigation: Wallet link for users, Billing Plans link for admins
