zeekay a4a9b8d0ec feat(verkle): integrate luxfi/crypto/banderwagon canonical
Rewrite 10 import lines across 9 verkle/*.go files to point at
luxfi/crypto/{banderwagon,ipa,ipa/{ipa,common}} instead of
crate-crypto/go-ipa/*. Drops crate-crypto/go-ipa from go.mod.

verkle tests: 82 PASS / 4 SKIP / 2 FAIL (known-stale upstream fixtures
TestParseNodeEoA, TestParseNodeSingleSlot — pre-existing on
[email protected], unchanged baseline).

go build ./... clean.
