feat(ui): port retail jump power bar

Import gmFloatyPowerBarUI LayoutDesc 0x21000072, teach the meter factory its stateful single-image shape, and project the movement-owned retail jump charge through a focused retained controller. Preserve authored resize constraints and state-managed visibility, with named-decomp pseudocode plus controller, movement, and production-DAT conformance coverage.
