chore: re-vendor client tarball types for the additive session-list currency field

[aarontrowbridge]

Problem — Slice 1 (PR #296) added an additive currency field to the v2 session-list response; the vendored client tarball's generated types predate it, so the client reads the field structurally until the vendor snapshot is refreshed.
Fix — Re-run the vendor snapshot so generated types include the field; nothing behavioral.
Source — PR #296 review notes; spec-20260905-045114 (D2).

Closing as moot: the fork is retiring (harness-agnostic re-base landed — amicode main runs the app overlay on canonical v1.18.29). The vendored client tarball this chore targeted no longer has a forward path; the currency field is now client-derived per spec-20260905-045114's placement amendment, so no vendored types are needed.
