feat(fp): WP-19 — Playwright e2e smoke against the real FE+backend

Adds a happy-path spec (login → dashboard → registratie wizard, including
a real identity-document upload → real submit) and a degraded-path spec
(?scenario=error → <app-async> error slot → retry), both driving the real
app against the real .NET backend, plus a CI job that boots both.

Writing the retry spec surfaced a real bug: AsyncComponent's retry() only
reloads a [resource]-fed instance, so every real page (all [data]-fed via
a store's RemoteData) had a silently no-op retry button. Added a
retryClicked output and wired it on the dashboard's two async blocks.

+## Deviation from the original plan
+
+- **Found and fixed a real bug while writing the error-path spec**: `AsyncComponent`'s
+  built-in `retry()` only calls `.reload()` on a `[resource]` input — every real page
+  (`dashboard`, `registration-detail`, `aanvraag-detail`, `brief`) feeds `<app-async>`
+  via `[data]` (a store's combined `RemoteData`), so clicking "Opnieuw proberen" was a
+  silent no-op everywhere except the showcase teaching page. Added a `retryClicked`
+  output that fires regardless of feed mode, and wired the two dashboard instances
+  (`BigProfileStore.reloadProfile()`/`reloadAantekeningen()`) since that's what this
+  WP's spec exercises. **Not fixed**: `registration-detail`, `aanvraag-detail`, and
+  `brief` pages still have the same latent no-op retry — same "found via testing,
+  fixing the whole surface is beyond this WP" call as WP-17's dashboard CSS finding.
+  Flagging here so it isn't lost.
+- Confirmed `currentScenario()` reads `window.location.search` fresh on every call —
+  the error-path spec's retry assertion had to change from "counts a browser network
+  request" (the scenario interceptor never reaches the real transport; it substitutes
+  `throwError` in the rxjs pipe before `next(req)`) to "observes a real Loading→Failure
+  reload cycle via `aria-busy`". The Steps section's literal suggestion ("assert it
+  re-fetches... via a network tab") didn't hold; adapted per the WP's own Risks note
+  to verify actual interceptor behavior first.
+- Verified the suite isn't a no-op per the Verification section: temporarily broke
+  `diplomaOptions`' `value: d.id` (appended `-x`), watched `smoke.spec.ts` fail on the
+  now-missing `#diploma-d1` selector, reverted.
+- The registratie wizard's minimum path needed an actual file upload (`identiteit` is
+  always required for `registratie` regardless of diploma choice, per
+  `DocumentRules.CategoriesFor` — only `diploma`/`taalvaardigheid` are answer-gated).
+  Picked the first DUO diploma (non-English, `Engelstalig: false`) specifically because
+  it carries zero policy questions, keeping the happy path to one upload.
+- CIBG-styled radios hide the native `<input>` behind its `<label>` — Playwright's
+  `.check()` on the input times out fighting the label for pointer events; the specs
+  click the `label[for=...]` instead (also more representative of a real click).
