fix(admin): shadow-DOM-aware plain keys, commit drafts before shortcut saves and safe My account links (B-WR-01, B-WR-02, B-WR-03, B-WR-06, B-IN-01)

- plain-key shortcuts test composedPath()[0], and a custom element inside a
  form counts as editable (closed shadow roots)
- Ctrl/Cmd+S and Ctrl/Cmd+Enter blur the focused field before clicking, so a
  pending taglist draft or native change is committed, then refocus it
- safeUrl keeps javascript:/data: URLs out of href and window.open
- a failed contributions GET shows a toast and keeps the sections; a section
  with error true shows an error line
- My account confirm and stale texts get their own phrase keys
- rebuilt modules/boardwalk/dist
