docs(base-account): HTTP links to Coinbase/Base properties in basenames FAQ

**Path:** `docs/sdks/base-account/basenames/basenames-faq.mdx`

## Description

Three links in the Basenames FAQ page use `http://` even though all three destinations are Coinbase/Base's own properties and serve over HTTPS:

- Line 28: `[Coinbase Verification](http://coinbase.com/onchain-verify)`
- Line 33: `[BNS name owner](http://basename.app)`
- Line 85: `[base.org/names](http://base.org/names)`

## Suggested fix

Update all three to `https://`. Verified each resolves correctly over HTTPS.

Apri docs/sdks/base-account/basenames/basenames-faq.mdx e controlla i tre link identificati alle righe 28, 33 e 85. Aggiorna ogni URL Coinbase/Base da http:// a https://, quindi verifica che i link vengano risolti correttamente e che la FAQ venga visualizzata senza problemi.
