What I did

Related issue
For compatibility, added the existing amount calculation logic to partial deposit flow

Sorry it took so long to get to this.

Simple enough PR but can we add a unit test to verify the proper usage of the multiplier? Would be nice to see one for the deposit flow as well if possible

Hey ! A few unit tests using the multiplier were added in commit 17ba390, mostly in tests/test_cli/test_new_mnemonic.py
I will add more tests in tests/test_cli/test_partial_deposit.py as well

Added more tests for partial deposit 👍
