fix(model-pricing): polish sync channel dialog layout

- keep input focus and invalid rings inside the shared Input component to avoid clipping in constrained containers.
- make the sync channel selector table use a fixed header, internal body scrolling, and fixed pagination inside the dialog.
- align status cells with their header and translate channel status labels through existing i18n keys.
