[PM-20287] Initialize login email state when email is remembered

[trmartin4]

🎟️ Tracking

https://bitwarden.atlassian.net/browse/PM-20287

📔 Objective

We currently set the email state when a there is input on the email or remember me form fields. However, this doesn't work if the user has "Remember Me" selected and attempts a subsequent login without editing the email address. This never fires the email input event and so the loginEmail is never persisted to state for that login flow.

This change sets the loginEmail if an email is remembered, ensuring that the field is initialized in sync with the remembered email if one exists.
