feat(design): adopt CIBG component patterns (header, forms, wizards, dashboard)

Re-skins the app's layout on top of the CIBG Huisstijl theme (previous commit) so it
matches designsystem.cibg.nl, not just its colour tokens — magenta ("robijn") header,
horizontal nav, and the CIBG component markup for forms/wizards/dashboard.

- Header: logo block + robijn titlebar (breadcrumb + user menu) + grey horizontal nav
  (4 links) replacing the dashboard side-nav; breadcrumb restyled for the titlebar
  (no background of its own — CIBG's global `header nav` rule otherwise bleeds a grey
  fill into it, fixed by scoping an override inside BreadcrumbComponent).
- Forms: form-field/radio-group/checkbox rebuilt on CIBG's horizontal `form-group row`
  / `form-check.styled` markup (label col-md-4, control col-md-8); same input() APIs.
- Wizards: stepper rebuilt as the CIBG "stappenindicator" (numbered circles, visited
  steps clickable for back-nav, title merged in); wizard-shell adopts the CIBG
  procesnavigatie button row. Back-navigation wired into all three wizard machines
  (registratie-wizard already had it; added `GaNaarStap` to intake/herregistratie
  machines, pure + spec'd).
- New shared/ui molecules: confirmation (animated bevestiging checkmark, replaces
  plain alerts on submit), review-section (controlestap sections with "Wijzigen"),
  application-list/application-link (CIBG "aanvragen" rows, replace the dashboard's
  card grid and aanvraag-block).
- Cleanup: delete side-nav and now-unused styles.scss utilities (.app-overview,
  .app-form-panel, .app-card-grid); correct design-tokens.mdx (it referenced tokens
  that no longer exist) and document the CIBG-value token bridge.

Verified: build/lint/check:tokens green, 178 tests pass (4 new GaNaarStap cases), and
manually driven end-to-end (dashboard, a full herregistratie submission through to the
confirmation screen, mobile width, keyboard focus).
