Added test CG10

[RyRy241]

This pull request implements the test case CG10, which verifies a one-day shift ending at 2022-10-31 17:00:00 using 15-minute reading intervals, and confirms that quantity unit conversion from kWh to BTU works correctly in the compare readings API. To support this test, we added:

Unit u16: BTU (quantity unit)

Conversion c3: MJ → BTU (bidirectional) with slope 947.8 and intercept 0

The test sets up units/conversions, fetches the dynamically assigned BTU unit ID from the DB, with shift=P1D, and asserts the returned values match the expected BTU results

Limitations

We were able to implement the code, but since time was limited, we weren't able to test the application to see if our test case worked as intended.
