chore(deps): bump lightning to 12.2.11 [AMB-3167]

[wthrajat]

v12 removes channel_capacity from payment hops. This repo mirrors some of lightning's types locally in src/server/modules/node/lightning.types.ts, and two of those mirrors still required the field, so the build failed:

`GetRouteToDestinationResult.route.hops[].channel_capacity` — removed, to match what v12 actually returns.
`PayViaRoutesHop.channel_capacity` — made optional. v12's `payViaRoutes` does not need it (it only validates channel ids and ignores unknown hop fields), and `trade.resolver.ts` still sets it on the synthetic hop it builds, so making it optional keeps both sides happy
