Sync docs and fix flaky renewal e2e test
- ARCHITECTURE.md: add Vault Endpoints section, /unseal UI page,
vault_sealed/vault_unsealed audit events, sealed interceptor in
gRPC chain
- openapi.yaml: add /v1/vault/{status,unseal,seal} endpoints, update
/v1/health sealed-state docs, add VaultSealed response component,
add vault audit event types and Admin — Vault tag
- web/static/openapi.yaml: kept in sync with root
- test/e2e: increase renewal test token lifetime from 2s to 10s
(sleep 6s) to eliminate race between token expiry and HTTP round-trip
