Exit status: real progress, blocks-left countdown, honest failures

submitpackage answers HTTP 200 even when it rejects the package — the
verdict hides in package_msg/tx-results — so a mainnet no-fee-coin exit
sat at 'publishing on-chain…' forever believing its bare hop had
relayed. Rejections now surface (and become the actionable needs-a-fee-
coin message on the bumpless path). The status line shows hop progress
(step 2 of 9), the timelock wait counts down in blocks with a rough
wall-clock estimate, and a stuck exit that never published anything
gets a 'Cancel this exit' link that returns the vtxo to spendable.
