feat(inventory): TrySpendAsync covers all 4 wallets + freeplay

Browse Source 
Crystal/Rupy/RedEther freeplay no-op (returns configured amount,
balance unchanged); SpotPoint always real. Insufficient returns
current balance; success returns post-deduction balance.
SVSimTestFactory gains freeplayEnabled ctor overload that upserts
the Freeplay GameConfigSection row after EnsureSeedData.
