`files` schema (encrypted-blob metadata)

[codebestia]

Create files table: id, ownerId → users.id, storagePath, size, mimeType, sha256 (of ciphertext), contentType (file/image/video/audio), createdAt, deletedAt. NO file key column — the key lives only inside the E2EE message envelope. Add relations + types.

Acceptance criteria:

• File metadata stored; no key material in DB
• sha256 of ciphertext stored for integrity
• Soft-delete via deletedAt
