Enhance address-sweep-spendable Behavior

Return Transaction for Inspection & Add Option to Sweep All Addresses

Summary

The address-sweep-spendable command currently broadcasts the transaction immediately, offering no opportunity for manual inspection. Additionally, the command requires specifying all addresses to be swept individually. This feature request proposes two enhancements:

1. Return the Transaction for Inspection
   Instead of automatically broadcasting, the command should return the raw transaction (similar to other commands), allowing users to review it before broadcast.

2. Option to Sweep All Addresses
   Introduce a parameter that, if set, sweeps all spendable balances (including return addresses) of the current wallet to the specified address in a single step.

Example

Wallet> address-sweep-spendable mtc1q****aaaa all
Sweeping all outputs of the current wallet to the address  mtc1q****aaaa
