Add durable buyer-bound Lightning recovery and explicit native retry

Preserve original invoice preimages, private snapshots and exposure provenance; serialize rail admission and retire native-only failures before explicit replacement. Qualify 55 focused UI tests and vue-tsc. Expanded 17 engine cases and combined backend acceptance remain pending; six earlier engine cases passed in isolation. No live payment or publication.
