Fix Solars, add IllegalComponent test.

[whatston3]

About the PR

Fixes the plasma/uranium solar panels to use our grid-based system.

Adds a test that checks all entities for illegal components in case we deprecate older systems (cough cough, solars).

Why / Balance

I goofed. Fixes https://discord.com/channels/1123826877245694004/1347163990492581908.

How to test

1. Put up some solars, at least one of each type on Frontier Outpost, make sure they're connected to HV power.
2. Spawn a solar control computer, set the angle to something obvious (e.g. 45 degrees)
3. Wait until the solar panels update.
