feat(onboarding): friendlier wizard bootstrap + Done screen starts the daemon

First-run bootstrap polish:
- Failed card wraps the (often long) error instead of clipping it, and offers a
  "Try mirror" button; Retry now keeps whichever source (main/mirror) was used.
- Bootstrap offer shows an honest size/time hint and relabels "Mirror" →
  "Use mirror" with a clearer tooltip.
- Daemon status dot/label is keyed off the EmbeddedDaemon::State enum instead of
  matching the English substring "Stopping" (which broke in every other
  language), and the faint ~55%-alpha label is raised to ~86%.
- Bootstrap Done screen: for the embedded daemon it now offers "Start Daemon"
  (and says the node will start) instead of telling the user to start it by hand.

Also carries the new string-table keys for these (and the shielded-card tooltip
used by the next commit).
