[Regression] All entities without reactors return 1000 to Lua getEnergy() and getMaxEnergy()

In 2024.12.08, SpaceShips return 1000 to getEnergy() and getMaxEnergy() if they lack a reactor, but other non-STBO entities such as asteroids return an error. On master, all entities, including non-STBOs, return 1000 energy and max energy if they lack a reactor.

Steps to reproduce

1. Place an Asteroid in a scenario.
2. Run the scenario.
3. Select the Asteroid in the GM screen
4. From the Lua console, run print(getGMSelection()[1]:getEnergy()) or print(getGMSelection()[1]:getMaxEnergy())

Expected behavior

The asteroid either returns a sensible value (such as 0) or throws an error. In 2024.12.08, the asteroid throws attempt to call a nil value (method 'getEnergy') or attempt to call a nil value (method 'getMaxEnergy').

Observed behavior

The asteroid returns 1000 for both.

Start by reproducing the issue with an Asteroid selected in the GM screen, then run getEnergy() and getMaxEnergy() from the Lua console. Compare the results on master with 2024.12.08. Done means entities without reactors no longer incorrectly return 1000, with behavior matching the selected expected outcome: a sensible value or an error.
