9202e67e33 feat: MCP server discovery UI (#21079)
* feat: add curated MCP server registry for discovery UI

Curated list of 31 well-known MCP servers with names, icons,
categories, transport config, and registry URLs. Includes HTTP
endpoints for GitHub, Atlassian, Sentry, Snowflake, and Cloudflare.

* feat: add GET /v1/mcp/discover endpoint for MCP discovery

Admin-only endpoint that serves the curated MCP registry with
optional query and category filters. Used by the UI discovery modal.

* feat: add DiscoverableMCPServer types for MCP discovery

* feat: add fetchDiscoverableMCPServers network function

* feat: add MCP discovery modal component

Compact list-row layout with category filters, search, and
grouped server list. Follows dev-tool aesthetic.

* feat: wire MCP discovery modal into server management page

Add MCP Server button now opens discovery modal. Card click
pre-fills the create form. Custom Server opens blank form.

* feat: add prefill from discovery and back-to-registry link

Create form accepts prefillData from discovery selection and
shows a Browse MCP Registry link to return to discovery modal.

* test: add unit tests for MCP discovery endpoint and registry

Tests for registry JSON structure validation and endpoint
query/category filtering logic. 15 tests total.
