Fix Failing Unit Tests

[StefanoFiumara]

While testing with temporary cards in Player.cs, the unit test assertions have gone out of sync, leading to failing tests.

• Move CardBuilder to test project, replace all uses of CardBuilder in the game project to reading from the Card Library- [ ]
• Replace the temporary cards created in PlayerSystem.cs with a parameterized version that the unit tests can take advantage of
• Increase test coverage in newly created systems
  • TODO: Document which systems need updated tests
