Where can I find the gory details of this construct used by glob/symbol-based modules

See Typeglobs and Filehandles in perldata.

Is there another way to access that hash?

If $sym contains 'fred', then ${*$sym}{hash_key} = 'something'; is equivalent to $fred{hash_key} = 'something';.

Or strictly:

our %fred;

$fred{hash_key} = 'something';

I can't find the equivalent of the STDIN example. Where is it stored? Is it a hash that's magically not accessible by name?

There is a hash (and array and scalar et al.) associated with the STDIN glob:

c:\test>perl -E"${*STDIN}{fred} = 'bill'; say $STDIN{fred}"
bill

they just aren't normally used for anything.
