feat: centralize fee logic and add Bitcoin deposit forwarding#3258
Conversation
Move getSendFeeRate() into BitcoinBasedFeeService using template method pattern, eliminating duplicate fee multiplier logic across Bitcoin and Firo services. Add dedicated Bitcoin deposit forwarding with explicit UTXO selection and subtract_fee_from_outputs for accurate fee handling.

Move UTXO-from-address fetching and input mapping into a shared sendManyFromAddress method on BitcoinBasedClient. FiroClient overrides it with its raw-transaction approach. Simplifies forwardBitcoinDeposit to a single method call.
