fix: presigned URL signatures, bucket consolidation, login & invite status

- MinIO: use separate public client for presigned URLs so AWS V4 signature
  matches the browser's Host header (fixes SignatureDoesNotMatch on all uploads)
- Consolidate applicant/partner uploads to mopc-files bucket (removes
  non-existent mopc-submissions and mopc-partners buckets)
- Auth: allow magic links for any non-SUSPENDED user (was ACTIVE-only,
  blocking first-time CSV-seeded applicants)
- Auth: accept invite tokens for any non-SUSPENDED user (was INVITED-only)
- Ensure all 14 invite token locations set status to INVITED
