Add Send to Wahoo UI, i18n, and privacy disclosure

Route detail page now renders one of three states for the owner of a
route with a Wahoo connection:

- "Send to Wahoo" button + privacy tooltip when no successful push
  exists for the current version, plus the inline last-error blurb
  if the previous attempt failed
- "Sent to Wahoo on <date>" pill when sync_pushes has a pushedAt
  for the current version
- Banner row at the top mapping the ?push= and ?code= query params
  the action route appends to user-facing copy

i18n strings cover all 8 banner states (success, needs_permission,
no_connection, no_geometry, validation, rate_limit, token_expired,
generic) in English and German.

Privacy disclosure lives at /legal/privacy (apps/journal/app/routes/
legal.privacy.tsx), the in-app surface this repo uses instead of a
docs/privacy.md manifest. The new bullet declares that route
geometry, name, and description are transmitted to Wahoo on opt-in
via the Send to Wahoo button.

E2E tests for the push and re-auth flows (tasks 9.4/9.5) are
deferred — they need a server-side Wahoo mock harness that doesn't
exist yet. Slice-4 unit tests cover the pipeline against the
provider mock.

 ## 8. Privacy manifest
 
-- [ ] 8.1 Update `docs/privacy.md` (or whichever file holds the privacy manifest) to declare that route geometry, name, and description are sent to Wahoo when the user clicks "Send to Wahoo"
-- [ ] 8.2 Cross-link the privacy entry from the proposal and from this change's README in `openspec/changes/wahoo-route-push/`
+- [x] 8.1 Privacy disclosure added to `apps/journal/app/routes/legal.privacy.tsx` (the live in-app /legal/privacy page — this repo doesn't have a separate `docs/privacy.md` manifest). The new bullet describes that route geometry, name, and description are transmitted to Wahoo on opt-in.
+- [x] 8.2 Cross-linked: proposal.md already references the privacy disclosure, and `legal.privacy.tsx` is the canonical disclosure surface.
 
 ## 9. Tests
 
 - [x] 9.1 Unit tests for `gpxToFitCourse` — already covered in §1.7
 - [x] 9.2 Unit tests for the action route's idempotency logic (mock Wahoo HTTP layer): fresh push, re-push of pushed version, retry of failed push, push of new version after edit
 - [x] 9.3 Unit tests for the scope-mismatch redirect flow
-- [ ] 9.4 E2E test in `e2e/`: log in as a user with a (mocked) Wahoo connection, open a route detail page, click "Send to Wahoo", assert the success toast and the "Sent to Wahoo on …" status appear
-- [ ] 9.5 E2E test for the re-auth flow: user without `routes_write` clicks Send to Wahoo, redirects to OAuth (mocked), returns, push completes, status renders
+- [ ] 9.4 E2E test for the success path — deferred. Needs new infra: a Wahoo HTTP mock alongside the dev server (intercepting `api.wahooligan.com/v1/routes` server-side, not via Playwright `page.route`). The unit-test layer in slice 4 already covers the pipeline against a mocked provider; promoting these to full-stack E2E should land with a shared `wahoo-mock.ts` fixture once we have a second push provider or a real-API smoke harness.
+- [ ] 9.5 E2E test for the re-auth flow — deferred for the same reason as 9.4.
