Add ability to pay BOLT11 invoices that don't have an embedded amount
by specifying the amount at payment time via the `amount_msat` parameter.
Changes:
- Add `Feature.amountless_invoice` to wallet base class for capability detection
- Update `Wallet.pay_invoice()` signature with optional `amount_msat` parameter
- Implement amountless invoice support in LND REST and LND gRPC wallets
- Update payment service layer to validate and pass through amount_msat
- Add `amount_msat` field to CreateInvoice API model
- Update all wallet implementations with new method signature
- Add tests for amountless invoice payment flow
Usage: POST /api/v1/payments with `amount_msat` when paying amountless invoices
