fix(mcp): remove SSE support; keep stdio default when type is omitted

- Backend: reject "sse" in validators; accept missing type as stdio; require url only for http (mcp.rs, claude_mcp.rs)
- Frontend: McpServer.type narrowed to "stdio" | "http" (optional) (src/types.ts)
- UI: avoid undefined in list item details (McpListItem)
- Claude-only sync after delete to update ~/.claude.json (commands.rs)

Notes:
- Ran typecheck and cargo check: both pass
- Clippy shows advisory warnings unrelated to this change
- Prettier check warns on a few files; limited scope changes kept minimal
