fix(ci): resolve all 3 CI/CD pipeline failures — green build

FRONTEND (lint error — exit code 1):
- AdminCoverage.tsx: moved fetchData above useEffect, wrapped in useCallback
- Fixes react-hooks/immutability: variable accessed before declaration
- Verified: npm run lint exits 0

BACKEND (pytest — exit code 5, no tests collected):
- Created tests/test_core.py: 28 comprehensive pytest tests covering:
* Config module (pydantic-settings loading)
* SearchQuery validation (XSS strip, language fallback, min length)
* IngestRequest + EligibilityRequest validation (bounds, defaults)
* chunk_text business logic (empty, short, overlap, whitespace)
* WhatsApp expiry alert payload generation (structure, defaults)
* Eligibility engine (PM Kisan farmer/non-farmer, income limits)
* Bhashini language maps (completeness, BCP47 format)
- Created pytest.ini to point test discovery at tests/ directory
- Verified: 24 passed, 4 skipped (openfisca), 0 failures, 0.90s

CI WORKFLOW:
- Fixed pytest command: pytest tests/ --cov=. --cov-report=xml -v
- Removed continue-on-error from pytest step so failures are real
- Added .gitignore for *.pyc files
