The root of your problems is that nginx has no such thing as
extension-based handlers. Only one location{} configuration matches any
particular request, and everything needed to process the request must be
specified in this location (or at higher level).

If you wish to serve *.php through fastcgi backend and static content with 
same url prefix directly from nginx, you should write two locations for 
each such url prefix - one for static content, and one for *.php. 
Something like this:

location /blog/wp-admin/ {
 	alias /var/www/wordpress/wp-admin/;
 	auth_basic ...
}
location ~ ^/blog/wp-admin/.*\.php$ {
 	alias /var/www/wordpress/wp-admin/;
 	auth_basic ...

 	fastcgi_pass ...
 	...
}

NOTE1: Not really checked, test before using. You probably will need some 
more tweaks to catch .../ -> .../index.php mapping.

NOTE2: Regex locations are tested in order, so please make sure you 
specified "location ~ ^/blog/wp-admin/.*\.php$" before "location ~ 
^/blog/.*\.php$" (and of course before "location ~ \.php$").

NOTE3: This is not performance-optimal solution, since all regex locations 
will be checked for all non-matching requests (but better than passing 
them to backends, of course). To achive maximum performance you should 
separate static and dynamic content (to eliminate regex locations 
completely).

To simplify things with multiple such locations you may use "include" 
directive (e.g. with fastcgi_* params).
