Feature Request: Add ability to import sites from LocalWP

### What

I'd like the ability to easily import sites from LocalWP (https://localwp.com), which is a competing product.

### Why

Many users use LocalWP to run local WordPress sites. This allows the user to import existing LocalWP sites into Studio and use Studio instead.

### How

_No response_

No files, tests, or entry points are identified. Start by reviewing how Studio currently imports or detects WordPress sites and how LocalWP stores them. Define the supported migration scope and acceptance checks before implementation.
