Description

The TFT→SPORE conversion currently sends the full transfer amount with no fee deducted. The refund path already
has a configurable fee (REFUND_FEE_PLANCK), but the forward conversion path does not.

Add a TRANSFER_FEE_PLANCK configuration (default 100,000 planck = 0.01 TFT) that is deducted from the
incoming TFT amount before calculating the SPORE output. Transfers where the amount is less than or equal to
the fee should be rejected as invalid.
