Lower internal buffer makes batteries important as external buffers
while keeping generation rate (5 power/lava) unchanged.

Battery now holds 25 smelts or 6 drill ops, serving as a real buffer.
Fluid container doubled to support lava generator chains better.
Visual thresholds updated to match new capacities.

Crusher: 2→4 power (ore doubling warrants 2x smelting cost)
Obsidian factory: 100→25 power (was absurdly expensive)
Small drill: 10→8 power, storage 10→16
Soft touch drill: 50→20 power, storage 50→40
Auto smelter/cobble factory: storage 2→4 (slightly bigger buffer)

Lava generator: add blaze rod (gates behind Nether access)
Crusher: add diamond (ore doubling is very powerful)
Small battery: 1→3 copper ingots (matches 5x storage increase)
Obsidian factory: add diamond (premium output deserves premium recipe)

Align all test assertions with new power costs, storage capacities,
and generation rates across solar panel, battery, lava generator,
drills, crusher, factories, and fluid container.

Crusher textures for all directional faces and powered states.
Soft touch drill textures and CraftEngine block configuration.

Add Crusher and SoftTouchDrill to power block factory, dialog display
names/descriptions, and test helpers. Update block count assertions.
