Summary

First step of k3s homelab deployment for dance-lessons-coach.

Adds the deployment scaffolding so the binary can be deployed to the ARCODANGE k3s homelab — pattern adapted from arcodange-org/webapp.

What's in this PR

Dockerfile : multi-stage Go alpine build (golang:1.26-alpine builder → alpine:latest runtime), runs swag init then go build ./cmd/server, exposes 8080
chart/ : minimal Helm chart with deployment, service, ingress, serviceaccount, configmap, helpers, NOTES
Ingress : dancecoachlessons.arcodange.lab via Traefik with crowdsec middleware
NodeSelector : pi1 (mirrors webapp pattern)
healthz : /api/healthz for liveness + readiness
values.yaml config block** : exposes DLC_LOGGING_*, DLC_DATABASE_*, DLC_API_V2_ENABLED via configmap → envFrom

Degraded mode

This first PR ships a "degraded mode" deployment :

❌ No database wiring (DB host empty in values)
❌ No SMTP (magic-link emails won't work yet)
❌ No Vault integration (no dynamic postgres creds, no kvv2 secrets)

Just serves the binary + swagger + healthz endpoints — enough to make https://dancecoachlessons.arcodange.lab/swagger/doc.json referenceable.

Verification

helm lint chart/                     # ✓ 1 chart(s) linted, 0 chart(s) failed
helm template chart/ --set image.repository=test --set image.tag=v1
                                     # ✓ produces ServiceAccount + ConfigMap + Service + Deployment + Ingress

Follow-ups (separate PRs)

Vault auth (VaultAuth + VaultStaticSecret + VaultDynamicSecret CRDs for SMTP creds + dynamic postgres)
Terraform iac/ for Vault config (kvv2 path + postgres role)
Gitea workflow for docker build + push to gitea.arcodange.lab/arcodange/dance-lessons-coach
Gitea workflow for tofu apply on iac/

Notes

Chart name : dance-lessons-coach (kebab-case, Helm convention)
ConfigMap chosen over config.yaml template name to avoid confusion with viper config
ASCII-safe everywhere except YAML literals

✨ feat(deploy): Dockerfile + Helm chart for k3s homelab deployment 6c23298625

Pattern adapted from arcodange-org/webapp.

Degraded mode : no DB / no SMTP / no Vault yet, just serves the binary +
swagger + healthz. Subsequent PRs will add Vault auth + Postgres dynamic
credentials + SMTP config.

Ingress route : dancecoachlessons.arcodange.lab (homelab internal).
