Fix EC2 provider settings keys for target-az and target-region (#2396)

The UI was sending camelCase keys (targetAz, targetRegion) in the
provider spec.settings, but the backend expects kebab-case keys
(target-az, target-region). This caused migration plans to fail
with "provider spec.settings.target-az is not configured" error
when creating EBS volumes from snapshots.
