Real bug affecting both home and VPS GitLab, found live diagnosing why
VPS's webservice pod was stuck at Init:0/3 for 74+ minutes (surfacing as
404s - nothing was ever actually serving):
global.appConfig.omniauth.providers: [{secret: gitlab-oidc-secret, key:
provider}] requires that secret to have a 'provider' key (a full YAML
omniauth provider config) - gitlab-oidc-secret never has one, only
GITLAB_OIDC_CLIENT_ID/SECRET, which get consumed via extraEnvFrom +
GITLAB_OMNIBUS_CONFIG's gitlab_rails['omniauth_providers'] instead (the
actual, complete mechanism already configuring OIDC - this providers:
list was always redundant). Removed it from both values.yaml files.
Home's GitLab has run fine so far because Kubernetes doesn't re-validate
already-mounted volumes when a referenced Secret's shape changes -
webservice/sidekiq there just haven't restarted since gitlab-oidc-secret
was last (if ever) in a shape with that key. VPS's identical values
shape hit it immediately on first pod creation. This was a live landmine
for home too - fixed before it could bite on a future restart.
Also: global.kas.enabled: false added to the VPS values (gitlab.kas.enabled
alone doesn't stop KAS pods - found live, separate toggle).

Gitaly CPU limit was 250m causing throttling on git operations (485ms
p99 to webservice). Increased to 1 core with 100m request. Also added
workerProcesses: 3 to webservice for better request concurrency
(was default 2).

Webservice was at 94% memory (1875Mi/2Gi) with only 50m CPU request,
causing CPU throttling and slow first requests after idle periods.
