fix(views): use fake timers globally in login-page tests to prevent input-otp timer leak

input-otp sets internal timers that fire after jsdom tears down window,
causing "ReferenceError: window is not defined" unhandled errors in CI.
Using fake timers suite-wide ensures no real timers escape after cleanup.
