Claude 1673c37b9c fix: comprehensive security hardening from full codebase audit
Addresses 14 findings from the security audit across all severity levels:

CRITICAL:
- C-1: Add user blocking system (migration, DB queries, REST API, WS DM
  send check) to prevent harassment via unconsented DMs
- C-2: Remove server version from unauthenticated /health and /info endpoints
  to prevent fingerprinting

HIGH:
- H-1: Remove dangerous-settings feature from tauri-plugin-http
- H-3: Default allowSelfSigned to false in API client (was hardcoded true)
- H-4: Cap invite expiration to 30 days (720 hours)
- H-5: Add 256KB message size limit to LiveKit WS proxy (prevents OOM)
- H-6: Cap concurrent sessions to 25 per user (evicts oldest on overflow)
- H-8: Restrict /diagnostics/connectivity to ADMINISTRATOR role

MEDIUM:
- M-2: Deny access to legacy NULL-uploader unlinked attachments
- M-4: Log warnings on TOTP plaintext decryption fallback paths
- M-8: Remove acceptInvalidCerts from OG preview fetches
- M-10: Expand file upload blocklist (Java .class, OLE2, WASM, .lnk)
- M-12: Add LIMIT to ListInvites (200) and ListMembers (1000)
- M-14: Add CHECK constraint trigger on channels.type (text/voice/dm)
