GUI polish: Help section, tooltips, sticky save bar + section nav, dashboard filters

- Help: shared help.js injects a Help modal (workflow + key concepts) and the
  .help-tip tooltip component. "❔ Help" added to the suite header and home nav.
- Tooltips: ⓘ hover hints on the trickiest fields (WP number auto-build,
  disciplines, scope/split, constraints, materials-by-discipline, discipline
  strategy, split threshold).
- WP creator: sticky section-nav jump chips at the top and an always-visible
  sticky save bar (Save Draft / Save & View) showing live release readiness.
- Dashboard: metric cards (Release-ready / On hold / Overdue / Total) and the
  status chips are now clickable filters for the board.
- Consistent colored status pills in the dashboard board and the saved list.

Theme unification (home Carbon vs tools palette) intentionally left for a
separate pass.
