fix: hide warning for weak password unless it actually applies [DET-10216]

[jesse-amano-hpe]

Ticket

DET-10216

Description

Think I accidentally resolved a rebase conflict incorrectly when I merged #9519 . This restores a missing if statement so the toast doesn't just display every single time.

Noticed and fixed during acceptance review with @hkumar92

Test Plan

Same as #9519
