🎨 Palette: Add dynamic ARIA attributes to interactive toggles

[secrooq]

💡 What: Added aria-expanded and dynamic aria-label attributes to multiple interactive toggles (mobile menus, profile dropdown, support widget) across the application. Also added aria-labels to previously unlabelled "X" close buttons within those menus.

🎯 Why: Static ARIA labels like "Toggle Navigation Menu" don't convey the current state to screen reader users. Without aria-expanded, users rely on guesswork to determine if an action opened or closed a menu. Dynamically updating the label to explicitly state "Open..." or "Close..." significantly improves the accessibility and usability of these components.

📸 Before/After: No visual changes. Purely semantic HTML improvements.

♿ Accessibility:

• Added aria-expanded={isOpen} to toggles.
• Added dynamic aria-label={isOpen ? "Close Menu" : "Open Menu"} to toggles.
• Added static aria-label="Close..." to internal drawer close buttons.
