feat(PROJ-36,PROJ-37): gzip-Kompression + Attachment-Deduplication

Browse Source 
Sprint 1: Emails werden vor AES-256-GCM optional gzip-komprimiert (compress: true).
Magic-Byte 0x01 als Prefix ermöglicht backward-kompatibles Load() für Legacy-Dateien.
Neue DB-Tabelle storage_objects trackt Kompressions-Metadaten.

Sprint 2: Attachments werden via SHA-256 dedupliziert — gleicher Anhang in N Mails
wird nur einmal gespeichert. Neue Tabellen: attachments, email_attachments.
