feat: bump LDK to include BLIP-42 contact secret support

Update rust-lightning dependency to include commit 40bd9e4 from PR #4210
which adds contact_secret and payer_offer fields to OptionalOfferPaymentParams
and create_compact_offer_builder to ChannelManager/OffersMessageFlow.

This enables passing BLIP-42 contact information through the standard LDK
payment API via OptionalOfferPaymentParams instead of requiring separate
handling.
