Docs updates for #97346

#97346 revised the Your spend label on Home from "Repaid in the last 30 days" to Repaid last 30 days (across all locales).

This updates the matching bold label in the Home overview help article so the docs reflect the current UI.

What changed

• docs/articles/new-expensify/getting-started/Expensify-Home-Overview.md — updated the Your spend bullet label from **Repaid in the last 30 days** to **Repaid last 30 days**.

The other in-prose mentions of "repaid in the last 30 days" (in the descriptions and the "Why don't I see the Your spend section?" FAQ) describe the 30-day timeframe as a concept rather than quoting the UI label, so they remain grammatically correct and unchanged.

The failing build check is unrelated to this PR — it's a transient Cloudflare infrastructure error, not a code problem, so there's no fix to push.

What happened: The docs site built successfully; the failure came at the very end during the Deploy to Cloudflare Pages step, when Wrangler got a 503 Service Unavailable from the Cloudflare API:

✘ [ERROR] Received a malformed response from the API
  upstream connect error or disconnect/reset before headers. reset reason: connection termination
  GET /accounts/***/pages/projects/helpdot -> 503 Service Unavailable

Why it's unrelated: This PR only changes one bold label in a single Markdown file (docs/articles/new-expensify/getting-started/Expensify-Home-Overview.md). A 503 from Cloudflare's deploy API is an outage on their side and has nothing to do with the content change.

Fix: Just re-run the failed job — re-run build. I attempted the re-run myself but don't have permission to trigger it here, so someone on the team will need to click Re-run failed jobs (or push any new commit) to clear it.
