1108810 - protect the complete private files directory

as a bonus, we improve this by using a simpler Directory directive instead of DirectoryMatch
move files and robots.txt rewrite rules to the vhost

this is to fix #1678876, as we can now access the site URI without
fooling around SERVER_NAME vs HTTP_HOST

move platforms dir creation away from server verification

this is a tentative fix for #1735174. the rationale is that the

bump up the SSL key size to 2048 bit
