Setup code quality actions

This page is a capture in the deferred bucket of the product backlog — a pre-sprint idea, not yet pulled into a sprint as a story.

We added a test password to the repo on purpose to see if it was going to be detected by the github actions:

std::string connection_string("postgresql://ores:ores@localhost:5433/oresdb");

It wasn't. We need to figure out which actions need to be setup for this. Add any other actions we may be missing.

The build seems to be failing:

-- SCCache NOT found.
 CMake Error at /usr/local/share/cmake-3.30/Modules/CMakeDetermineSystem.cmake:152 (message):
   Could not find toolchain file:

 Call Stack (most recent call first):

 CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.

 cpp/autobuilder: No supported build command succeeded.
 cpp/autobuilder: autobuild summary.
 Error: We were unable to automatically build your code. Please replace the call to the autobuild action with your custom build steps. Encountered a fatal error while running "/opt/hostedtoolcache/CodeQL/2.18.0/x64/codeql/cpp/tools/autobuild.sh". Exit code was 1 and last log line was: cpp/autobuilder: autobuild summary. See the logs for more details.

This may be due to a missing sub-module for vcpkg.
