Use submitted name if possible and server as fallback for MCP installation

[StefELianos]

Linked issue:

#416

Summary

• Fixes MCP install deeplink name selection so it uses the submitted MCP component name instead of defaulting to the config key (often server).
• Preserves previous fallback behaviour by using server when the component name is empty/missing.
• Keeps MCP config payload handling unchanged; only the deeplink name parameter selection is adjusted.

Problem

When adding an MCP via Add to Cursor, the deeplink name could show as server even when a custom name was provided, because the name was derived from the config structure rather than the component display name.

Solution

In apps/cursor/src/components/plugins/detail/mcp-section.tsx:

• Stop deriving deeplink name from mcpServers keys.
• Use mcp.name.trim() for install deeplinks.
• Fall back to "server" if that name is blank.

Note

Low Risk
Narrow change to deeplink name query parameter only; no auth, data, or config parsing changes beyond dropping unused name from resolveMcpConfig.

Overview
MCP “Add to Cursor” install deeplinks now pass the plugin component’s display name (mcp.name) instead of the first mcpServers config key (often server).

resolveMcpConfig only returns the parsed config; name selection moved to install-link generation with mcp.name.trim() || "server" when no explicit mcp_link is set. Config payload and preview behavior are unchanged.
