How AI was used in this PR

AI was used to develop code, which I reviewed and tested across different LocalWP sites.

Proposed Changes

• Add "Import from Local" option to the Add Site flow. Allows importing from LocalWP (https://localwp.com)
• Reads LocalWP's sites.json to detect sites.
• Exports database using LocalWP's MySQL.
• After import, update site URL to Studio's localhost address and deactivate plugins (which may rely on MySQL-specific features or force HTTPS). On complex sites, plugins would cause crashes.

Testing Instructions

• Install and configure sites via LocalWP (https://localwp.com)
• Sites will be detected in Studio, import the site, and it will copy contents from LocalWP and configure.
• Test site loads as expected

Pre-merge Checklist

• Have you checked for TypeScript, React, or other console errors?

Hey @MxchaelA8C ! "Import from a backup" already supports importing sites exported from Local. What prevents you fro using that feature?

Hey @wojtekn - thanks for sharing that. I wonder if it could be made clearer in the app and in the documentation. I completely missed that this was possible. I'd expect the docs label "Import & Export" https://developer.wordpress.com/docs/developer-tools/studio/import-export/ to somewhat match "Import a backup" that's displayed in the app.

I did search "Local" on the docs before looking into adding this feature, but that's not the most searchable term to surface the information, and the fact that the docs for Studio are shared with WP.com makes searching pretty difficult.

I wonder if some tweaks to the wording or aspects of the UI could help guide users more effectively and make this clearer.

Happy to hear your thoughts :)

Love the work on Studio so far. It's a really great product.
