Kelly 4949b22457 feat(tasks): Refactor task workflow with payload/refresh separation
Major changes:
- Split crawl into payload_fetch (API → disk) and product_refresh (disk → DB)
- Add task chaining: store_discovery → product_discovery → payload_fetch → product_refresh
- Add payload storage utilities for gzipped JSON on filesystem
- Add /api/payloads endpoints for payload access and diffing
- Add DB-driven TaskScheduler with schedule persistence
- Track newDispensaryIds through discovery promotion for chaining
- Add stealth improvements: HTTP fingerprinting, proxy rotation enhancements
- Add Workers dashboard K8s scaling controls

New files:
- src/tasks/handlers/payload-fetch.ts - Fetches from API, saves to disk
- src/services/task-scheduler.ts - DB-driven schedule management
- src/utils/payload-storage.ts - Payload save/load utilities
- src/routes/payloads.ts - Payload API endpoints
- src/services/http-fingerprint.ts - Browser fingerprint generation
- docs/TASK_WORKFLOW_2024-12-10.md - Complete workflow documentation

Migrations:
- 078: Proxy consecutive 403 tracking
- 079: task_schedules table
- 080: raw_crawl_payloads table
- 081: payload column and last_fetch_at

-- Migration 080: Raw Crawl Payloads Metadata Table
-- Per TASK_WORKFLOW_2024-12-10.md: Store full GraphQL payloads for historical analysis
--
-- Design Pattern: Metadata/Payload Separation
-- - Metadata (this table): Small, indexed, queryable
-- - Payload (filesystem): Gzipped JSON at storage_path
--
-- Benefits:
-- - Compare any two crawls to see what changed
-- - Replay/re-normalize historical data if logic changes
-- - Debug issues by seeing exactly what the API returned
-- - DB stays small, backups stay fast
--
-- Storage location: /storage/payloads/{year}/{month}/{day}/store_{id}_{timestamp}.json.gz
-- Compression: ~90% reduction (1.5MB -> 150KB per crawl)
CREATE TABLE IF NOT EXISTS raw_crawl_payloads (
id SERIAL PRIMARY KEY,
