[Balance Idea]: Buff T3 naval support factory cost to match T2 factory efficiency

### Intended Change

T3 naval support factory cost: 2200 m, 11000 e, 10800 bt -> 1800 m, 9000 e, 8800 bt

### Reasoning

T2 naval factories are an outlier in terms of buildpower per mass:
| Factory| Mass | Buildpower | Mass/BP |
|--------|--------|--------|--------|
| T1 Naval | 300 | 20 | 15.0 |
| T2 Naval| 1100 | 90 | 12.2 |
| T3 Naval| 2200 | 150 | 14.7 |
| T3 Naval Buffed| 1800 | 150 | 12 |

For comparison, engineers are 10.4, 10.0, and 9.6 mass/BP.
The reason that I don't follow the typical idea of higher tech factories being less efficient to fix this inconsistency, is because it is more interesting to provide a way to spam frigates from a dense source of buildpower instead of occupying the entire ocean with T1 factory spam.
Frigates are also very expensive for a T1 unit, so there is no issue with rolloff taking too long or blocking pathfinding. Even a 150 buildpower T3 factory takes 8.3-9.7 seconds to build a frigate (depends on faction).
It's also satisfying to not have frigates take an entire minute to be built like in a T1 factory.

T3 factories are not much different from T2 factories in unassisted utility, so they should match T2 factories.

The reason to still make T2 factories in this scenario is that they have 2000 buildtime while T3 factories have 8800 buildtime. Which is actually an indicator of an issue with how buildtimes and buildpower is balanced in naval stages but I digress,

### Expected behavior

There would be no more weird pattern where upgrading from T2 to T3 significantly reduces your buildpower efficiency. There would be a consistent "higher tech = more efficient" trend for naval factories.
