fix: clear cached region when api_key changes via config set

Previously, switching API key with `mmx config set --key api_key`
kept the old cached region, causing requests to hit the wrong
endpoint. Now setting api_key deletes the cached region so it
gets auto-detected on the next command.

Bump version to 1.0.10.
