Data Table and Knowledge Base components are listed in the Embedded workflow editor

## Problem

The **Data Table** (`dataTable`) and **Knowledge Base** (`knowledgeBase`) components show up in the Embedded (Integration) workflow editor — both in the node-picker popup and in the right-sidebar component list.

Data Tables and Knowledge Bases are Automation-only resources; there is no embedded ownership for them, so an integration workflow cannot use them meaningfully.

## Cause

The embedded component list is served by `ComponentDefinitionApiController` (embedded) with `PlatformType.EMBEDDED`, which applies `IntegrationComponentDefinitionFilter`. That filter only excludes `apiPlatform`, `codeWorkflow` and `webhook`.

## Fix

Add `dataTable` and `knowledgeBase` to the excluded component names in `IntegrationComponentDefinitionFilter`.
