Should we note somewhere in user docs that this affects non-JIT channels?

Hmm, I'd rather not honestly, as communicating what risks this entails requires to get super technical and arguably the inflight value is much too low for non-forwarding nodes anyways (and we can probably assume a node using LSPS2 JIT invoices won't be a central routing node in the network). Still, I want to get this fixed soon, hopefully even by 0.0.122.

When we're an LSPS2 client, the LSP might open the channel to us with a capacity only barely more than the initial payment size. We therefore need to be able to receive close to 100% of the channel size in a single HTLC. Here we therefore bump the default max HTLC value inflight config to 100%. We should eventually be able to set this on a per-channel basis, but for now we just bump the default for all channels.
