fix: recovery passphrase flow (#5877)

Description
---
Switches the handling of wallet recovery passphrase entry to require
confirmation and provide complexity analysis.

Closes #5859.

Motivation and Context
---
When recovering a wallet from a seed, the user is prompted to enter a
passphrase without confirming it, and the passphrase complexity is not
checked. That is, the flow is the same for wallet recovery as for
opening an existing wallet, which is incorrect.

This PR switches the flow to that of a new wallet. When the user enters
a passphrase, they must confirm it, and its complexity is analyzed to
ensure the user is informed of the safety of their chosen passphrase.

Note that each case (new wallet, wallet recovery, existing wallet) is
now handled separately. This is mildly redundant, but allows for better
logging and makes the intent more clear.

How Has This Been Tested?
---
Tested manually.

What process can a PR reviewer use to test or verify this change?
---
Assert that the passphrase handling logic is now correct. Manually test
empty, weak, and strong passphrases in the interface, including the case
where the user has a weak or empty passphrase and confirms this is their
intent.
