Describe the bug
Description:
There are a couple of problems in the login flow:

1. Backend is not returning the correct error message — it sends authIncorrectPassword, which looks like a localization key, not the actual user-facing message.

2. Frontend doesn’t properly display errors — it should display whatever error the backend returns, and if there’s nothing from the backend, show a default error message. It shouldn’t default to “incorrect password” unless that’s the actual error.

To Reproduce
Steps to reproduce the behavior:

1. Go to the Login page.
2. Enter a invalid email and a password.
3. Observe that the backend returns authIncorrectPassword as the message.

Expected behavior
Backend should return a valid, translatable error key or a proper message.

Frontend should display the exact message from the backend.
