1. In `frontend/src/pages/Auth/Login.jsx`, change the email Input component's `type` prop from `"text"` to `"email"`.

The email validation condition in the SignUp page (`frontend/src/pages/Auth/SignUp.jsx`) uses `&&` operators which creates incorrect logic. The condition `!validateEmail(email) && !email.endsWith(".com") && !email.includes("@")` requires all three sub-conditions to be true simultaneously to show an error, meaning invalid emails like `"test.com"` (missing @) or `"user@example"` (missing .com) would incorrectly pass validation.

## Changes that Need to be Made

1. In `frontend/src/pages/Auth/SignUp.jsx`, change the email validation condition on line 55 from `&&` to `||` so that the error is triggered when ANY of the validation checks fail.

Change from:
```
if (!validateEmail(email) && !email.endsWith(".com") && !email.includes("@"))

Change to:
```
if (!validateEmail(email) || !email.endsWith(".com") || !email.includes("@"))

The `protect` middleware in `backend/middlewares/authMiddleware.js` uses `token.startsWith("Bearer")` which is case-sensitive. According to RFC 7230, HTTP headers are case-insensitive. Some clients or proxies may send `bearer` in lowercase, causing valid tokens to be rejected with "Not authorized, no token".

## Changes that Need to be Made

1. In `backend/middlewares/authMiddleware.js`, change the token prefix check to be case-insensitive:

Change from:
```
if (token && token.startsWith("Bearer")) {
```

Change to:
```
if (token && token.toLowerCase().startsWith("bearer")) {

In `frontend/src/context/userContext.jsx`, the `setLoading(false)` call is made in both the `catch` block (line 50/52) and the `finally` block (line 55).

Additionally, the second API call for sheet progress (lines 57-62) is not inside a try-catch, meaning errors there will propagate unhandled.

## Changes that Need to be Made

1. In `frontend/src/context/userContext.jsx`:
   - Remove `setLoading(false)` from the `catch` block (line 52) since the `finally` block already handles it
   - Wrap the second API call (lines 57-62) in a try-catch to prevent unhandled errors
