Fix WearablesConfig create reentrancy

[cinnabarhorse]

Moves WearablesConfigFacet.createWearablesConfig state updates (push + slotsUsed increment) before any ETH transfers.

Why:

• The previous ordering allowed a reentrant owner/treasury contract to create another config before the outer call had persisted its slot usage, leading to slot/id desync (outer call returns id 0 but stores at index 1).

Tests:

• npx hardhat test test/wearablesConfigReentrancy.test.ts
