this pull req changes the implementation of the challenge database and entities

it now stores we and me challenges and the related extra inforrmation

using the fastapi docs to test methods may not result in expected behavior because the json information passed does not include any typing, however using resetdb all functions work as expected and the database can be updated with the correct information.

reset db now loads a starting wechallenge.

future TODOs will include whatever functions are necessary to update particular fields such as saving a challenge by a user, likewise to the example many of these rely on other things being implemented first so we will address them as it comes

changes made, also updated the devcontainer dockerfile, apparently it needs to be slightly diff for the production one.
