jony376 aaade3530e fix(api): cap memory message limit and top_n at REST_API_MAX_PAGE_SIZE (#15376)
## Related issues

Closes #15375

### What problem does this PR solve?

`GET /api/v1/messages` and `GET /api/v1/messages/search` accepted
unbounded `limit` / `top_n` query parameters while other REST list
endpoints enforce `REST_API_MAX_PAGE_SIZE` (100) via
`validate_rest_api_page_size()`. Oversized values can trigger expensive
memory index queries and large result sets (DoS risk).

### Type of change

- [x] Bug Fix (non-breaking change which fixes an issue)

### Changes

| File | Change |
|------|--------|
| `api/apps/restful_apis/memory_api.py` | Cap `limit` and `top_n` with
`validate_rest_api_page_size`; return argument error when exceeded |
|
`test/testcases/test_web_api/test_message_app/test_message_routes_unit.py`
| Regression tests for oversized `limit` / `top_n` |

### Test plan

- [x] Unit tests added
- [ ] `pytest
test/testcases/test_web_api/test_message_app/test_message_routes_unit.py`

(1). Deploy RAGFlow services and images

https://ragflow.io/docs/build_docker_image

(2). Configure the required environment for testing

Install Python dependencies (including test dependencies):

uv sync --python 3.13 --only-group test --no-default-groups --frozen

Activate the environment:

source .venv/bin/activate

Install SDK:

uv pip install sdk/python 

Modify the .env file: Add the following code:

COMPOSE_PROFILES=${COMPOSE_PROFILES},tei-cpu
TEI_MODEL=BAAI/bge-small-en-v1.5
RAGFLOW_IMAGE=infiniflow/ragflow:v0.26.3 #Replace with the image you are using

Start the containerwait two minutes:

docker compose -f docker/docker-compose.yml up -d


(3). Test Elasticsearch

a) Run sdk tests against Elasticsearch:

export HTTP_API_TEST_LEVEL=p2
export HOST_ADDRESS=http://127.0.0.1:9380  # Ensure that this port is the API port mapped to your localhost
pytest -s --tb=short --level=${HTTP_API_TEST_LEVEL} test/testcases/test_sdk_api 

b) Run http api tests against Elasticsearch:

pytest -s --tb=short --level=${HTTP_API_TEST_LEVEL} test/testcases/test_http_api 


(4). Test Infinity

Modify the .env file:

DOC_ENGINE=${DOC_ENGINE:-infinity}

Start the container:

docker compose -f docker/docker-compose.yml down -v 
docker compose -f docker/docker-compose.yml up -d

a) Run sdk tests against Infinity:

DOC_ENGINE=infinity pytest -s --tb=short --level=${HTTP_API_TEST_LEVEL} test/testcases/test_sdk_api 

b) Run http api tests against Infinity:

DOC_ENGINE=infinity pytest -s --tb=short --level=${HTTP_API_TEST_LEVEL} test/testcases/test_http_api
