Why
Clicking the “Continue” button on the login page no longer triggered the submission logic. The issue was introduced when `useState`/`useContext` hooks were destructured incorrectly, breaking the setter reference and omitting required values.

What’s changed
• **LoginForm.js**
  – Re-added setter in `useSearchParams` (`[searchParams, setSearchParams]`).
  – Corrected order of destructuring for `inputs` so `username`/`password` are available after hooks.
  – Switched `useContext` to `[userState, userDispatch]` for consistency.

• **RegisterForm.js**
  – Adopted `[userState, userDispatch]` from `UserContext` to mirror LoginForm and retain full state access.

Outcome
Login button now successfully invokes `handleSubmit`, and both auth components have consistent, fully-featured hook destructuring, preventing runtime errors and ensuring future state usage is straightforward.
