- Add prompt-injection fencing to _webhook_memory_content (was missing
the --- BEGIN/END EXTERNAL DATA --- fence applied elsewhere)
- Wrap Content-Length parsing in try/except to avoid 500 on malformed
header values
- Move _to_gateway_read below imports (was incorrectly placed between
import blocks) and tighten transformer types
- Replace list-rebuild with deque.popleft in rate limiter for O(expired)
amortized pruning instead of O(n) per call
- Make organization_id required in send_session_message to prevent
fail-open cross-tenant check

send_gateway_session_message only required basic auth (AUTH_DEP) while
all other gateway endpoints required ORG_ADMIN_DEP. Any authenticated
user could send messages to any gateway session. Now requires org-admin
and verifies the board belongs to the caller's organization.
