Phase 0: Project restructure to ReviewIQ platform architecture

New structure:
- scrapers/google_reviews/v1_0_0.py (was modules/scraper_clean.py)
- scrapers/base.py (BaseScraper interface)
- scrapers/registry.py (ScraperRegistry for version routing)
- core/database.py, models.py, config.py, enums.py
- utils/logger.py, crash_analyzer.py, health_checks.py, helpers.py, date_converter.py
- workers/chrome_pool.py
- services/webhook_service.py
- api/ routes structure (empty, ready for Phase 2)
- tests/ structure mirroring source

All imports updated in:
- api_server_production.py (7 import paths updated)
- utils/health_checks.py (scraper import path)

Legacy modules moved to modules/_legacy/:
- data_storage.py, image_handler.py, s3_handler.py (unused)

Syntax verified, frontend build passing.
