Add BYOK / CIE org-size disclosure and soften CIE in-app search keyword

Per follow-up review on PR #71:

- Add a second top-of-page :::note callout on both bring-your-own-api-key.mdx
  and custom-inference-endpoint.mdx clarifying that BYOK and CIE are
  available to individual users and organizations with 10 or fewer
  employees; larger organizations need a Warp Business or Enterprise plan.
- Mirror the same disclosure as a one-sentence statement near the bottom
  of each page so readers who jump to the BYOK Enterprise/Business section
  (BYOK) or the Plan availability section (CIE) see the restriction inline.
- Soften the CIE 'Enabling' step from 'search for custom inference endpoint'
  to 'search for inference endpoint' since the exact configuration name
  was not verifiable.
