fix: fixed database connection URL

Removed the @ensureContext(true) decorator from the login method as it was breaking the request object, preventing authentication in YDB.

In the Driver class constructor, replaced `origin` with `host`, as `origin` returned `null`, which caused the database connection to fail.
