lib: Fix compiler warnings with GCC 16 / Python 3.14

Browse Source 
sim_find.cpp: Python 3.14's pyconfig.h redefines _POSIX_C_SOURCE and
_XOPEN_SOURCE to older values, but only if they haven't been defined yet.
Moving <Python.h> to be the first include (before any system header that
pulls in features.h via <string>) prevents the -Wmacro-redefinition
warnings that become errors under -Werror.

usrprio_rpc_client.cpp: Value-initialize usrprio_device_info to silence
-Wmaybe-uninitialized on the interface_num member, caught by GCC 16.
