The vector -> JetStream -> ClickHouse chain duplicated storage the in-cluster VictoriaLogs already provides, and its NATS StatefulSet keeps the logging Application from syncing.
- collect pod logs with a VLAgent DaemonSet remote-writing to vlinsert-logs
- delete vector, NATS, ClickHouse, logarchiver and logviewer
- drop clickhouse-system from the logging ApplicationSet

## Why
The Vector archiver leg wrote gzip NDJSON to S3 with no index or encryption. logarchiver replaces it with a Go service that seals raw logs to S3 as zstd + OpenPGP objects and indexes each object in ClickHouse (`logs.archive_index`), acking JetStream only after the object is stored and indexed.
## Changes
- Add logarchiver Deployment (`git.unkin.net/unkin/logarchiver:v0.1.0`), ConfigMap, and dedicated ServiceAccount, reusing the archiver's NATS (`log-consumer` / durable `archiver` / `ARCHIVE_SUBJECTS=logs.k8s.vault.>`), S3 (`logs-archive-s3`), ClickHouse (`clickhouse-credentials`) and `vault-ca` wiring.
- Encrypts to the `logarchive` gpg public key, fetched from the gpg engine via k8s auth (role `logging_logarchiver`, projected vault-audience token). `ack_wait` (5m) > batch `max_age` (2m) so messages aren't redelivered mid-batch.
- Add `logs.archive_index` DDL to the clickhouse-schema bootstrap Job (no TTL — outlives `logs.raw`).
- Remove the vector-archiver Helm release, values and pipeline ConfigMap.
Cross-repo: apply **terraform-vault #106** (gpg key + role/policy) before this syncs, or the pod can't fetch the public key. Sequencing: apply after #306 (already merged).
