Password Reset with Valid But Non-Existent User ID Returns Unhandled 500

Is there an existing issue for this?

Current behavior

When I follow a password reset link that contains a valid base64-encoded but non-existent user ID, the server crashes with an unhandled DoesNotExist exception and I see the error message attached below:

User.DoesNotExist: User matching query does not exist.

What I expect is a redirect to the error page with a clear message that the reset link is invalid.

File: apps/api/plane/authentication/views/space/password_management.py — ResetPasswordSpaceEndpoint.post() calls User.objects.get(id=id) but only catches DjangoUnicodeDecodeError, leaving User.DoesNotExist unhandled

Steps to reproduce

1. Construct a password reset URL with a valid base64-encoded UUID that doesn't correspond to any user
2. 2. Submit the reset form
3. 3. See 500 error instead of a redirect to the error page
