Implement User Account Settings Page

[armanist]

We need to introduce a new "Account Settings" page, accessible from the top-left dropdown menu, where the user's name is currently displayed along with "My Posts" and "Sign Out."

Page Details

The page will have a simple UI with two tabs:

Profile Tab:

Inputs: First Name, Last Name (both required)
Allows users to update their profile information
Password Tab:

Inputs: Current Password, New Password, Confirm Password
Allows users to change their password

UI Requirements

Use Materialize CSS (no custom CSS)

Backend Implementation

Create a new AccountController.php with the following methods:

form() – Displays the account settings page
update() – Updates the user’s profile (first name, last name)
updatePassword() – Updates the user’s password
Implement new middlewares for validation:

Account.php – Ensures first name and last name are required
Password.php – Checks if the current password is correct and validates password confirmation

Additional Requirements

Display a success message after successful updates
Show appropriate validation error messages on failure
