Sri Varshitha 71f360d315 feat(tools/postgres-list-tables): Add new tool postgres source (#1284)
## Description
---
This pull request introduces a new custom tool kind
`postgres-list-tables` that allows users to list tables within a
Postgres database.

### Example Configuration

```yaml
tools:
  postgres_list_tables:
    kind: postgres-list-tables
    source: postgres-source
    description: Use this tool to retrieve schema information for all or specified tables. Output format can be simple (only table names) or detailed.
```

### Example Request
``` 
curl -X POST http://127.0.0.1:5000/api/tool/postgres_list_tables/invoke \
-H "Content-Type: application/json" \
-d '{
    "table_names": "users",
    "output_format": "simple"
}'
```
