feat: wire Credits page to pricing management and payment APIs

Updated CreditsPage with full pricing and transaction support:
- Load pricing packages from /api/packages (role-specific)
- Create payment orders via /api/payments/create-order
- Display transaction history from wallet ledger + payments
- New tabbed interface: Overview, Buy Credits, Transactions
- Shows package details: name, price, tracecoins amount
- Format currency in INR with proper locale

Data sources:
- Packages: GET /api/packages?role={role_key}
- Wallet: GET /api/{prefix}/wallet/me
- Ledger: GET /api/{prefix}/wallet/me/ledger
- Payments: POST /api/payments/create-order
