zaviermeekz-cpu c50f9c59aa fix: allow zero message history window and clear history for new sessions (#15897) (#15902) ...

### What problem does this PR solve?

Two bugs in the Agent Categorize component:
1. The backend rejected `message_history_window_size = 0` while frontend
allowed it, causing API errors.
2. When calling the agent API without a `session_id`, a new session was
created but retained history from previous conversations.

### Type of change

- [x] Bug Fix

### How has this been tested?

- Issue 1: `CategorizeParam().check()` now accepts `0` and rejects
negative values.
- Issue 2: `canvas.clear_history()` is called for new sessions (no
`session_id`), ensuring fresh conversation state. Verified via UI and
API that a second call without `session_id` does not remember the first
conversation.
