Fix LlamaParse 401 + update logo to v5

- Add LLAMA_CLOUD_BASE_URL config option so the LlamaCloud regional
  endpoint can be set without code changes (fixes 401/region errors
  on production); pass it through to AsyncLlamaCloud client init
- Document LLAMA_CLOUD_BASE_URL in .env.deploy.example with EU endpoint
- Copy BAR-ModComms-logo-v5.png to frontend/public
- Sidebar: update logo reference v4 → v5
- PDF header: update logo v4 → v5, wrap in black (#000) band for
  legibility, remove duplicate "Oliver" wordmark
