26f8238499 fix(login): correctly redirect to /password when ignoreUnknownUsername is set (#11130)
Closes #11006 

# Which Problems Are Solved

This PR addresses an issue where the ignoreUnknownUsernames setting was
not being respected in certain scenarios during the login flow.
Specifically:

- When a user was found but rejected due to login settings (e.g.,
disableLoginWithEmail), the system would return a "User not found" error
instead of redirecting to the password page as dictated by
ignoreUnknownUsernames.
- When a user was not found, and the flow fell through the registration
checks (e.g., IDP redirect failed), it would also return "User not
found" without checking ignoreUnknownUsernames.

# How the Problems Are Solved

- Introduced a helper function `handleUserNotFound` in 
`apps/login/src/lib/server/loginname.ts` to centralize the logic for
checking ignoreUnknownUsernames and redirecting to the password page.
- Updated the user validation logic to call handleUserNotFound when a
user is found but rejected by policy.
- Updated the registration fallback logic to call handleUserNotFound
instead of directly returning an error.
- Added new test cases in `apps/login/src/lib/server/loginname.test.ts`
to verify the fix and ensure no regressions.

# Additional Changes

- Fixed inconsistency in translation files
