fix(log): move sa_initiator struct outside get_sa() function

Browse Source 
- src/libipc/platform/win/get_sa.h:
  * Move 'struct initiator' definition outside get_sa() function
  * Rename to 'sa_initiator' to avoid naming conflicts
  * Define at namespace ipc::detail scope (above get_sa function)
  * Keep template constructor: template <typename Logger> sa_initiator(Logger const &log)
  * get_sa() now simply uses: static sa_initiator handle(log);

This fixes the C++ standard violation:
  - C++03/11/14/17/20 all prohibit local classes from having member templates
  - Error C2892: 'local class shall not have member templates'
  - Moving the struct to namespace scope resolves this issue

The struct is now a proper namespace-level definition with a template
constructor, which is fully compliant with C++ standards.
