Fix Menril Resin and Liquid Chorus fluids being non-interactable in world

[Copilot]

Both custom fluid blocks were missing block properties required by Minecraft/NeoForge for standard fluid behavior, making it impossible to place blocks in fluid space or pick up fluid with a bucket.

Root cause

BlockFluidMenrilResinConfig and BlockFluidLiquidChorusConfig were missing four block properties that vanilla fluid blocks (water/lava) require:

Property	Effect of absence
.replaceable()	Blocks cannot be placed where the fluid is
.liquid()	Bucket interaction silently fails (item consumed, no pickup)
.pushReaction(PushReaction.DESTROY)	Incorrect piston behavior
.noLootTable()	Loot table generated for fluid block

Fix

// Before
(eConfig, properties) -> new BlockFluidMenrilResin(properties
        .noCollision()
        .strength(100.0F))

// After — matches vanilla water/lava block property pattern
(eConfig, properties) -> new BlockFluidMenrilResin(properties
        .replaceable()
        .noCollision()
        .strength(100.0F)
        .pushReaction(PushReaction.DESTROY)
        .noLootTable()
        .liquid())

Applied identically to both BlockFluidMenrilResinConfig and BlockFluidLiquidChorusConfig.

Tests

Added GameTestsFluids with four game tests covering block replacement and BucketPickup.pickupBlock() for both fluids.

Set block as player instead via an itemstack, because calling setBlock like this will not trigger a replaceable check.

[Copilot]

Updated in b12dd89 — both replaceable tests now use helper.placeAt(player, dirtStack, POS.south(), Direction.NORTH) which calls ItemStack.useOn() via a UseOnContext, which in turn creates a BlockPlaceContext that checks canBeReplaced() on the fluid block at POS before allowing placement.
