[PM-43206] Inputting transaction amount in Fifth Third prompts to save password

### Steps To Reproduce

1. Open Fifth Third and go to transfer money to another account.
2. Input the dollar amount in "Other amount" and tap "Save".
3. Bitwarden will prompt to save the dollar amount (formatted as "$0.00") as a password.

### Expected Result

Bitwarden should not prompt to save a password.

### Actual Result

Bitwarden prompts to save your transaction amount as a password.

### Screenshots or Videos

### Additional Context

Just as a note: I am not 100% sure if this is reproducible in other banking apps, as I do not use any others.

### Issue Tracking Info

- [x] I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

No source file or test is named in the report. Start by reproducing the issue in the Fifth Third transfer flow on Android, then trace the Android save-password prompt triggered after entering the formatted amount. Done means the amount no longer produces a password-save prompt while normal password-saving behavior remains intact.
