perf: separate blob storage for registratura attachments

Root cause: even with SQL-level stripping, PostgreSQL must TOAST-decompress
entire multi-MB JSONB values from disk before any processing. For 5 entries
with PDF attachments (25-50MB total), this takes several seconds.

Fix: store base64 attachment data in separate namespace 'registratura-blobs'.
Main entries are inherently small (~1-2KB). List queries never touch heavy data.

Changes:
- registry-service.ts: extractBlobs/mergeBlobs split base64 on save/load,
  migrateEntryBlobs() one-time migration for existing entries
- use-registry.ts: dual namespace (registratura + registratura-blobs),
  migration runs on first mount
- registratura-module.tsx: removed useContacts/useTags hooks that triggered
  2 unnecessary API fetches on page load (write-only ops use direct storage)

Before: 3 API calls on mount, one reading 25-50MB from PostgreSQL
After: 1 API call on mount, reading ~5-10KB total
