fix(backend): Further enhance sanitization of SQL raw queries (#11279)

Browse Source 
### Changes 🏗️

Enhanced SQL query security in the store search functionality by
implementing proper parameterization to prevent SQL injection
vulnerabilities.

**Security Improvements:**
- Replaced string interpolation with PostgreSQL positional parameters
(`$1`, `$2`, etc.) for all user inputs
- Added ORDER BY whitelist validation to prevent injection via
`sorted_by` parameter
- Parameterized search term, creators array, category, and pagination
values
- Fixed variable naming conflict (`sql_where_clause` vs `where_clause`)

**Testing:**
- Added 4 comprehensive tests validating SQL injection prevention across
different attack vectors
- Tests verify that malicious input in search queries, filters, sorting,
and categories are safely handled
- All 10 tests in db_test.py pass successfully

### Checklist 📋

#### For code changes:
- [x] I have clearly listed my changes in the PR description
- [x] I have made a test plan
- [x] I have tested my changes according to the test plan:
  - [x] All existing tests pass (10/10 tests passing)
  - [x] New security tests validate SQL injection prevention
  - [x] Verified parameterized queries handle malicious input safely
  - [x] Code formatting passes (`poetry run format`)

#### For configuration changes:
- [x] `.env.default` is updated or already compatible with my changes
- [x] `docker-compose.yml` is updated or already compatible with my
changes
- [x] I have included a list of my configuration changes in the PR
description (under **Changes**)

*Note: No configuration changes required for this security fix*
