test(mcp): update test to reflect new MCP sync architecture

Remove MCP-related assertions from sync_codex_provider_writes_auth_and_config
test since provider switching no longer triggers MCP sync in v3.7.0+.

MCP synchronization is now handled independently by McpService,
not as part of the provider switch flow.
