iamtoruk 8a3fa69fe9 fix(app): real currency conversion, provider ids in picker, yield provider scoping
- formatUsd applies the payload currency {code,symbol,rate} once at
  display; formatConverted (symbol only) for CLI-preconverted plan
  values so nothing converts twice
- provider picker built from providerDetails: label shown, internal id
  sent as --provider (fixes filters for providers whose display name
  differs, e.g. Grok Build); falls back to map keys on older CLIs
- getYield threads the active provider through preload/main/sections

App suite 170/170, root 1615/1615.
