feat(menu): improve visual structure with cards, icons and timeline

[sumitakhuli]

Description (Fixes #369 )

This PR addresses the need for a Better Visual Structure for the Menu Display by implementing a modern, card-based layout for the daily menu and a visual timeline for the weekly schedule.

Key changes:

• Card Layout for Today's Menu: Replaced simple buttons with large, icon-based toggle cards (SunIcon for Lunch, MoonIcon for Dinner).
• Visual Timeline: The weekly menu is now displayed as a connected vertical timeline with circular day indicators, improved spacing, and card-based day headers.
• Color Coding: Added distinct accent colors (Orange, Purple, Green, Pink) to different food categories (Main, Special, Salad, Dessert) for easier scanning.
• Enhanced Styles: Used Syne font consistently and applied specific border colors/shadows to align with the design system.

Motivation and Context

The previous menu display was functional but lacked visual hierarchy and engagement. The new design makes it easier for users to distinguish between meal types and scan the weekly schedule at a glance.

How Has This Been Tested?

Tested locally in the development environment:

1. Toggle: Verified that clicking Lunch/Dinner cards correctly switches the displayed menu.
2. Timeline: Verified that the weekly menu renders as a connected timeline.
3. Responsive: Checked layout on mobile and desktop breakpoints.
4. Dark Mode: Verified that colors adapt correctly (using useColorModeValue) to dark mode.

Aesthetically i am more biased to the simpler version although some novelty could be nice. The single letters for the days i find a bit redundant.
