fix(2): Q3.4 — cryptpad Phase-2 (revised; create-pad deeper test deferred with rationale)

Initial Q3.4 (commit 0fb1458) shipped two tests that failed cold:
- test_api_config.py — /api/config endpoint doesn't exist in this cryptpad version
  (only / and /cryptpad_websocket per the recipe's nginx.conf.tmpl). REMOVED.
- test_pad_create.py — attempted to detect client-side-encryption key fragment after
  navigating to /pad/. CryptPad's pad-creation flow is version-specific; this release
  (10.6.0+5.7.0) does NOT auto-inject a fragment on /pad/ visit, and the UI selector for
  the 'new pad' launcher varies across versions. Deeper test deferred.

Revised:
- tests/cryptpad/functional/test_spa_assets.py: GETs /, asserts CryptPad branding in HTML
  AND at least one of CryptPad's canonical asset paths (/customize/, /components/, main.js,
  /api/broadcast). Non-vacuous: catches the wedged-cryptpad-server-fallback-page case.
- tests/cryptpad/playwright/test_pad_create.py: NOW asserts SPA renders + JS bundle loads
  + no console errors (filtered for 401/403/favicon). Documents the create-pad deeper test
  as deferred in-file. The maximal testable subset per §7.1 is what's shipped here.
- PARITY.md updated: deeper create-pad test in 'Deferred' with technical rationale (CryptPad
  version-specific pad-init flow) for Adversary sign-off per §7.1.

Cold-verifiable on cc-ci (log /root/ccci-q34-cryptpad-r4.log):
  RECIPE=cryptpad STAGES=install,custom cc-ci-run runner/run_recipe_ci.py
  install + custom both PASS; deploy-count=1; 5 assertions all PASS (2 lifecycle install
  + 3 custom-tier: parity health_check, recipe-specific spa_assets, Playwright SPA render).
