Minor wallet recover fixes

[ignopeverell]

Couple of those are security sensitive:

1. Do not log the recovery phrase on error.
2. Prompt for the phrase instead of passing it as a command arg so it doesn't appear in any command line history.

Good catch on log. I tried to fix the recovery phrase entry issue earlier in the same way, but found it a bit problematic from a UX experience, see: #2174

Basically, (at least on my system) stdin ignores any keymaps, so any attempt to erase or hit arrow keys as you're typing just creates a bigger mess. Agreed doing it this way is better than leaving it in your shell history, but still.. hmm..

1 ) ____ 2) ____ 3) _____ (print to 12 or 24)
(Q to quit, 1-24 to edit a word)

Type word 1 > pants

1 ) pants 2) ____ 3) _____ (print to 12 or 24)
(Q to quit, 1-24 to edit a word)

Type word 2 > yeast

Something like this? And bonus points if we can figure out the equivalent of typing ‘stty erase ’, to ensure delete works

Fun little recovery phrase widget from your intro to programming with Pascal class.

Ah, missed #2174. Not sure what's this UX thing you're talking about though.

Btw, hate to keep adding more dependencies but isn't that what readline is for? We could pick a Rust port (like https://github.com/murarth/linefeed).

Only problem with that linefeed crate is that I didn’t know it existed until now.
