fix(audit,web,deploy): audit ids, web dry-run view, hardened chart, docs

Audit: correlation event_ids include stage and response code so the
multi-stage lines of one request no longer collapse under dedup; match
scans are bounded to a time window and a page instead of the object's full
history.

Web: dry-run results are read from dry_run_result (nested) so the verdict is
rendered correctly and conflicts/errors/skipped are shown; the plans view no
longer POSTs an unsolicited plan on page load; coverage and streams surface
API errors instead of showing a misleading empty state and follow cursor
pagination so they are not stuck on the oldest page; the diff path tokenizer
handles backslash-escaped dotted keys.

Deploy/CI: the chart no longer grants the query server a cluster-wide read
ClusterRole, runs as non-root with a read-only root filesystem, adds
liveness/readiness probes, wires the ConfigMap as env (STORE_PATH,
LISTEN_ADDR), defaults the journal to a PVC instead of an ephemeral
emptyDir, and adds imagePullSecrets; the replay ClusterRole drops the
unused update verb; a Dockerfile builds a static distroless image; GitHub
actions are pinned by commit SHA, jobs set least-privilege permissions, the
Vercel deploy skips fork PRs, CI passes the Makefile test timeouts, and
make lint runs a real web syntax check.

Docs: event-schema/consistency no longer describe an ingest_sequence field,
an observed-time-based event_id, or restart-from-checkpoint; the threat
model documents the unauthenticated HTTP API surface and the chart's RBAC
change; replay-safety matches the enforced dry-run gate.
