fix: Call onToggleRecoverPassword(false) on “Back to sign in”

What kind of change does this PR introduce?

Bug fix.

What is the current behavior?

• Tapping “Forgot password” correctly triggers onToggleRecoverPassword(true).
• Tapping “Back to sign in” does not trigger onToggleRecoverPassword(false).
• As a result, parent widgets relying on this callback remain stuck in the “Recover Password” state (e.g., titles or layouts don’t update back).

Related issue: Fixes #147

What is the new behavior?

• Tapping “Back to sign in” now triggers onToggleRecoverPassword(false) after the internal state switches back from recovery, keeping parent UI in sync.
• Entering the recovery flow via “Forgot password” continues to trigger onToggleRecoverPassword(true) as before.
• Parent widgets relying on this callback (e.g., to update titles/layout) immediately reflect the correct state when leaving the password recovery view.
• No breaking changes; existing onToggleSignIn behavior remains unchanged.

Additional context

• No breaking changes.
• Minimal patch touching only the callback invocation on the “Back to sign in” action.
• Tested manually on mobile and web; no performance implications expected.
