fix: regenerate Alby Hub v1.23.0 patches against exact upstream source

Patch 1 (0001-private-route-hints.patch):
- Add missing RouteHints: hints, context line (v1.23.0 added this field
  between Expiry and Private; old patch lacked it, causing hunk failure)
- Fix amountMsat parameter name in hunk header (was 'amount' from older version)
- Only regular invoice Private field is changed; MakeHoldInvoice keeps
  Private: !hasPublicChannels unchanged

Patch 2 (0002-isolated-invoice-app-id.patch):
- Fix CreateInvoice interface: amountMsat uint64 (not amount uint64)
- Fix MakeInvoiceRequest: Amount/AmountSat/AmountMsat are *uint64 pointers
  (not Amount uint64) matching v1.23.0 struct layout
- Fix MakeInvoice call: 9 args → 10 args with appId as 8th positional arg
  (nil, nil trailing) matching v1.23.0 signature
- Fix function impl parameter: amountMsat uint64 throughout

Both patches dry-run verified against exact v1.23.0 source and apply cleanly
in sequence. Updated NixPatchContractTests to assert v1.23.0 context
(RouteHints, amountMsat, *uint64 pointer types, 10-arg MakeInvoice call).

All 233 Python tests pass. JS syntax checks pass.
