fix: update MCP server URL in documentation and examples

[AnkanSaha]

This pull request significantly redesigns the "MCP Section" of the LandingPage in client/src/app/page.tsx to provide a more visually engaging and informative overview of the MCP (AI-native control plane) and how to connect to it from various clients. The update introduces new UI elements, richer content, and improved code snippet presentation, while removing the previous, simpler version of the section.

Key changes:

MCP Section Redesign:

• Introduced a new visually rich "MCP Section" featuring a glow backdrop, badge, headline, endpoint bar, and a grid listing all 15 available tools with color-coded indicators.
• Added a "Connect in one step" area with terminal-style code snippets for six different AI clients, each with their own icon and color-coded code lines for improved clarity and aesthetics.

Content and Endpoint Updates:

• Updated endpoint references throughout the section from api.edge.nexoral.in/mcp to apiedge.nexoral.in/mcp for consistency and accuracy.

Removed Old Section:

• Removed the previous, more basic MCP section, which included a simple description, a list of tools, and static code snippets for each client.

UI/UX Improvements:

• Enhanced user experience with animation effects, improved layout, and better grouping of information, making it easier for users to understand the MCP's capabilities and how to connect from different clients.

These changes collectively modernize the MCP section, making it more user-friendly and visually appealing while providing clearer guidance for connecting to the MCP server.
