Add MinIO storage + replace Supabase Storage with S3 SDK

- New: src/lib/storage.ts — S3-compatible client, uploadFile/deleteFile/listFiles/publicUrl helpers, bucket constants
- New: docker-compose adds minio + minio_init services
- Replaced Supabase fetch PUTs in:
  - src/actions/brand-settings.ts (3 uploaders)
  - src/actions/products/upload-image.ts
  - src/actions/communications/import-contacts.ts
  - src/app/api/water-photo-upload/route.ts
- Replaced hardcoded Supabase URLs in:
  - src/components/storefront/TuxedoVideoHero.tsx
  - src/components/time-tracking/TimeTrackingFieldClient.tsx
  - src/app/tuxedo/about/page.tsx
  - src/lib/email-service.ts (4 occurrences)
- Added @aws-sdk/client-s3 + @aws-sdk/s3-request-presigner
- .env.example adds MinIO + storage vars
- Migration cleanup: deleted BUNDLE_018_042, 4 XXX drafts, 087/145/099-contact storage migrations
- Migration patches: 006 STATIC→STABLE, 135 param reordering
- Preflight: added pgcrypto extension, removed storage stub
- Verified: MinIO upload/list/delete round-trip works against local instance
