Deploy real GitLab on the VPS (not just Gitea)

Browse Source 
User wants actual GitLab on the VPS, not just Gitea's pull-mirror -
deliberate scope increase from the original plan's 'keep the VPS
lighter' design for git hosting specifically.

Simplified single-node equivalent of apps/gitlab (home) - same chart
version (7.7.0), same Authentik OIDC provider/client_id (added a second
redirect_uri to the shared GitLab provider in infrastructure/authentik/
gitlab-blueprint.yaml), same known chart bugs already diagnosed at home
(redis-init-fix.yaml for the initializer-ordering bug) - but:
  - 1 CNPG instance (local-path) instead of home's 3-instance HA
  - No Praefect - pointless HA routing with a single Gitaly node
  - No PgBouncer - direct CNPG connection, traffic is low enough
  - No SAML, no Container Registry, no KAS - addable later if needed
  - Own Traefik Ingress + https-redirect Middleware from the start
    (found needed the hard way on Vault/Gitea/n8n/Nextcloud/Authentik
    earlier this session - applying that lesson here immediately)

New Vault paths this needed: secret/vps/gitlab-redis (freshly generated,
this Redis instance is new, nothing to reuse) and widened the
vps-eso-reader policy to also allow secret/gitlab-oauth (the shared
Authentik client, already used by home's GitLab).

# Same fix as apps/gitlab/manifests/redis-init-fix.yaml (home) - GitLab
# chart 7.7.0's initializer ordering bug: 7_prometheus_metrics.rb loads
# before 7_redis.rb (alphabetical 'p' < 'r'), triggering Redis cache
# access before Gitlab::Redis::ALL_CLASSES is defined. This ConfigMap
# provides an early initializer that loads the Redis module first.
#
# Mounting this into webservice/sidekiq deployments still has to be a
# manual kubectl patch after first deploy - chart 7.7.0 doesn't support
# extraVolumes on those workloads, same limitation home hit, and home's
# own patch was never git-tracked either (applied live). See this
# directory's own deploy notes for the exact patch commands.
