feat(pe-guide): unified single-play + remove badges; fix(e2e): shared fixture + raised login limit

User-visible changes:
- Removed the REAL / SYNTH badge from each sound card. User feedback:
  "ridiculous". Cards now just show the sound title + description +
  player, no distinction beyond the player type (native <audio controls>
  for recordings, play/stop/progress bar for synth).
- Removed the "real recordings; synth labelled SYNTH" subtitle from
  the sounds library header.
- Single-playback policy across the whole PE Guide: when any sound
  starts (audio or synth), every other playing sound stops. Covers:
  audio → audio (pause the previous), audio → synth, synth → audio,
  synth → synth. Listeners attach on each .pe-audio 'play' event and
  on every synth play-button click.

E2E infrastructure fixes (for the test failures we hit):
- auth-gated-smoke.spec.js now imports test + loginAs from the shared
  fixtures.js so the token cache is unified across every spec. Without
  this, each spec file's module-scoped _tokenCache multiplied logins
  and hit the 10/15min rate limit.
- server.js: /api/auth/login rate limit is now configurable via
  LOGIN_RATE_LIMIT_MAX env var (default 10, prod unchanged).
- docker-compose.e2e.yml: LOGIN_RATE_LIMIT_MAX="500" so Playwright's
  two-project (chromium + mobile-chrome) multi-worker runs can do
  their logins without tripping the cap. Prod container unaffected.
- fixtures.js console.error allowlist expanded to suppress known
  non-bugs: Cross-Origin-Opener-Policy warnings on http:// e2e
  server, transient 401/403/404/503 resource loads, ERR_BLOCKED_BY_CLIENT.
