feat(dedup): CDC sub-file deduplication with FastCDC + parallel chunk storage + dedup skip
- Replace whole-file SHA-256 dedup with FastCDC 2020 content-defined chunking
(min 64KB, avg 256KB, max 1MB) + BLAKE3 hashing
- Add chunk_manifests table (file_hash → chunk_hashes[] + chunk_sizes[])
- Add put_blob_from_bytes to BlobStorageBackend trait (all 7 backends)
- 3-phase store_chunks pipeline:
Phase 0: batch-check existing chunks (single PG query)
Phase 1: selective disk read (skip existing chunks entirely)
Phase 2: parallel upload with buffer_unordered(8)
- CDC-aware read_blob_stream and read_blob_range_stream with legacy fallback
- Transactional manifest + chunk ref-count cascade on remove_reference
- 12 CDC tests (determinism, reassembly, contiguity, sub-file dedup, etc.)
- Update deduplication.md to reflect new architecture

feat: pluggable storage backends (S3, Azure, local) with admin UI
Implement 4-phase external storage backends architecture:
Phase 1 - Foundation:
- BlobStorageBackend trait (application/ports/blob_storage_ports.rs)
- LocalBlobBackend: extracted all tokio::fs ops from DedupService
- S3BlobBackend: AWS SDK with custom endpoint support (MinIO, R2, B2)
- DedupService refactored to use Arc<dyn BlobStorageBackend>
Phase 2 - Admin Panel:
- StorageSettingsService with DB persistence + env override
- Storage tab in admin panel (backend selector, S3 form, provider presets)
- GET/PUT/POST endpoints for storage settings + connection test
- i18n keys (en/es) and BEM CSS
Phase 3 - Migration:
- MigrationBlobBackend decorator (dual-read: target-first + source fallback)
- Background migration job with parallel transfers + progress tracking
- Migration UI (progress bar, ETA, pause/resume/verify/complete)
- 6 admin API endpoints for migration lifecycle
Phase 4 - Enterprise Extras:
- CachedBlobBackend: LRU disk cache for remote backends
- EncryptedBlobBackend: AES-256-GCM at-rest encryption
- AzureBlobBackend: Azure Blob Storage support
- RetryBlobBackend: exponential backoff for transient errors
- Decorator composition in DI: retry → encryption → cache
All 223 tests passing, clippy clean, fmt verified.
