refactor: use direct registry API call for server detail page

[peppescg]

Summary

• Replace the multi-registry Promise.all fan-out in the server detail page with a single direct API call to /registry/{registryName}/v0.1/servers/{serverName}/versions/{version}
• Thread the registryName from the catalog list page to the detail page via a URL query parameter, eliminating unnecessary API calls
• Fall back to fetching the default registry when the query param is absent (e.g. direct URL navigation)
• Remove the unused CATALOG_ALL_REGISTRIES constant and "All registries" select option

Test plan

• Unit tests updated and passing (21/21)
• TypeScript type-check passes
• Biome lint passes
• Navigate to a server detail page from the catalog — verify server name, description, and tools load correctly
• Navigate directly to a server detail URL (without ?registryName=) — verify fallback works

Pull request overview

Refactors the catalog server detail flow to avoid multi-registry fan-out by carrying the selected registryName from the catalog list into the detail page (via query param) and using a single direct registry API call, with a fallback to the default registry for direct URL navigation.

Changes:

• Remove the “All registries” option/constant and treat registry selection as a concrete registry name.
• Append ?registryName= when navigating from the catalog list to a server detail page.
• Update the server detail server-action to resolve the registry (query param or default) and issue a single direct API request.
