Two of the systemic error-surfacing foundations from the UX audit: - util::friendlyRpcError() maps the common raw daemon/JSON-RPC errors (warming up / -28, locked / -13, method-not-found / -32601, insufficient funds, unreachable node) to short translated guidance with a next step, falling back to the trimmed raw text. Wired into the send (money) path: the toast shows the friendly cause, the overlay keeps the raw text below it for diagnostics. The helper is reusable for the remaining raw-error sites. - Toasts now pause their auto-dismiss while hovered and ellipsize over-long text with the full message in a hover tooltip, instead of hard-clipping it mid-word (durations were already lengthened earlier).
