Description:
Add Restful endpoints in read_service for querying Crime data from the stlouis_gov_crime table (ensure columns: id, created_on, data_posted_on, is_active and necessary coloumns). Use SQLAlchemy for queries, filter only active records (is_active=1).

Acceptance Criteria:

• Endpoints: GET /api/crime (paginated JSON response, only active data).
• Inline docstrings and unit/integration tests (pytest + Flask test client).

Notes: Research and mention the source site (e.g., https://www.stlouis-mo.gov) in your PR title/description (e.g., "Add Crime API - Site: stlouis-mo.gov"). Update this issue with the exact site URL once confirmed. Ensure data_posted_on is parsed from site timestamps during ingestion.
