List memories scoped by filters with paginated results. Entity IDs (`user_id`, `agent_id`, `app_id`, `run_id`) must be passed inside the `filters` object: top-level entity IDs are rejected with 400. Expired memories are hidden by default. Pass `show_expired: true` to include memories whose `expiration_date` has passed. The `filters` object supports complex logical operations (AND, OR, NOT) and comparison operators:

- `in`: Matches any of the values specified
- `gte`: Greater than or equal to
- `lte`: Less than or equal to
- `gt`: Greater than
- `lt`: Less than
- `ne`: Not equal to
- `icontains`: Case-insensitive containment check
- `*`: Wildcard character that matches everything

Pass `page` and `page_size` as query parameters to paginate through results.

### Query Parameters

- `page`: integer (default: 1) - 1-indexed page number. Required range: `x >= 1`
- `page_size`: integer (default: 100) - Results per page. Required range: `1 <= x <= 200`

### Body

- `filters`: object (required) - Entity and metadata filters. Must include at least one entity ID (`user_id`, `agent_id`, `app_id`, or `run_id`).
- `show_expired`: boolean (default: false) - When true, include memories whose `expiration_date` has passed. Expired memories are hidden by default.

### Response

- `count`: integer (required) - Total number of memories matching the filters.
- `next`: string<uri> | null (required) - URL for the next page, or `null` if this is the last page.
- `previous`: string<uri> | null (required) - URL for the previous page, or `null` if this is the first page.
- `results`: object[] (required) - List of memory objects.
