"""Tests for the /credits command — shared view core + gateway handler.

`/credits` is the focused money surface (balance in, top-up out). These tests
exercise the surface-agnostic `build_credits_view()` core and assert the gateway
handler renders the block + tappable top-up URL + no-wait copy. The CLI panel is
a thin wrapper over the same view (interactive prompt_toolkit modal — covered by
the view-core tests plus manual verification).
