MPP.Session.Payload (mpp v0.15.0)

Session credential payload schema, discriminated on action.

Wire JSON uses camelCase action names ("open" / "topUp" / "voucher" / "close"). Elixir atoms are snake_case (:open / :top_up / :voucher / :close). Field names match the TIP-1034 precompile payloads in mppx Protocol.ts and mpp-rs SessionCredentialPayload.
