fix #1659 installation issue on PostgreSQL by ntroducing a new RewriteValue method which can be overridden in a database provider to provide custom behavior. Updated PostgreSQL provide to utilize new method. Also added an Oqtane.Server project reference to the module and theme external templates to streamline the development experience (credit @leighpointer).
