The legacy Blazor channel list let you drag-and-drop rows to reorder channel numbers. The SPA
(`App.tsx`) instead offers a "Renumber" action that walks the list and asks for each channel's new
number via a sequence of native `prompt()` calls. Deliberate deviation: drag-to-reorder needs a
dedicated drag library and a bespoke reorder-persistence endpoint; a sequential prompt reuses the
existing per-channel update call and needs no new UI dependency. Revisit only if channel counts grow
large enough that prompt-per-channel becomes tedious.
