[Feature]: Add richer `serverInfo`

[jancurn]

Problem or motivation

MCP protocol supports quite of bit of meta data in serverInfo (see docs):

interface Implementation {
  icons?: Icon[];
  name: string;
  title?: string;
  version: string;
  description?: string;
  websiteUrl?: string;
}

But we only pass:

{
    "name": "apify-mcp-server",
    "version": "0.10.11",
    "websiteUrl": "https://mcp.apify.com"
}

Proposed solution

Let's include more stuff, e.g. icons, title ("Apify MCP server"), description ("Use same info we have in MCP registry"). Apify will look better for clients that support it.

Alternatives considered

Implemented in #968 - extends the initialization serverInfo with title, description, and icons, reusing the constants server_card.ts already shares (new SERVER_DESCRIPTION constant prevents drift).
