fix(welcome): add missing SSH i18n keys + vertical SSH host/port layout

- Add connectSshPanelTitle, connectSshSubtitleHermes/Openclaw/Ironclaw to en locale
- These keys were already referenced by the component but missing from en/welcome.ts,
  causing raw key strings (welcome.connectSshPanelTitle) to display in the UI
- Change .welcome-ssh-grid to flex-direction: column so SSH Host and Port
  stack vertically instead of side-by-side

Fixes user-reported SSH panel display issues.
