refactor(canvas): drop Upstash entirely after successful DO migration

Browse Source

Production migration ran cleanly (samples_checked: 9, mismatches: []),
canvas data preserved, drawing verified by user. Phase 4 cleanup:

Removed code:
- src/lib/canvas-storage.js (Upstash GETRANGE reader)
- src/lib/redis-client.js   (Upstash REST helpers)
- src/lib/rate-limiter.js   (orphan since Phase 2)
- src/admin/migrate-from-upstash.js (one-shot importer)
- src/durable-objects/canvas-room.js #handleImport route
- src/durable-objects/lib/chunk-storage.js importFullCanvas helper
- src/worker.js /admin/migrate-from-upstash mount + import

Removed tests:
- test/lib/canvas-storage.test.js
- test/lib/redis-client.test.js
- test/integration/redis-canvas-roundtrip.test.js
- test/durable-objects/canvas-room.test.js (was skipped pending rewrite)
- vitest.integration.config.js (only Redis testcontainers used it)

Removed deps:
- @upstash/redis, ioredis, testcontainers (-184 packages)

Removed constants:
- REDIS_KEY_PREFIX, REDIS_CANVAS_KEY (only used by deleted code)

Removed package.json scripts: test:integration, test:all
Removed CF Worker secrets in production:
  UPSTASH_REDIS_REST_URL, UPSTASH_REDIS_REST_TOKEN, MIGRATION_TOKEN

Tests: 94/94 pass (down from 112 — 18 deleted Upstash-specific).
Bundle: 71.90 KiB (down from 79.43 KiB).
Production verified: canvas data intact (38% non-zero bytes), migration
endpoint returns 404, secret list empty.
