fix: build-verify tollgate_core component extraction

- Remove display/cvm/font deps from CMakeLists (not yet merged branches)
- Add tollgate_platform.h include to session header
- Add tollgate_core_session_set_platform declaration
- Remove duplicate tollgate_core_dns_stop wrapper (dns module has own impl)
- Update captive_portal.c to use tollgate_core_* API
- Remove display/cvm calls from tollgate_main.c
- Add tollgate_get_platform declaration to config.h
- Fix nucula wallet.hpp submodule (save_proofs visibility)
- Add tollgate_core include paths to test Makefile
- Build passes, all unit tests pass (61/61)
