remove .catchall() for connectorMetadataGuard

.catchall() allows unknown keys to be parsed as metadata. This is troublesome when we want to strip out unknown keys (Zod provides .strip() for this purpose but somehow it doesn't work with .catchall()).

For data extensibility, we added customData field to ConnectorMetadata type to store unknown keys. For example, the fromEmail field in connector-logto-email is not part of the standard metadata, so it should be stored in customData in the future.
