Add step-ca TLS certs for mysql, php, desktop, signage, fc-landing

RKE2 Traefik has no ACME certResolver configured, so IngressRoutes
using certResolver: step-ca silently fall back to the Traefik default
self-signed cert. Fix by using cert-manager Certificate resources with
the step-ca-acme ClusterIssuer and tls.secretName in IngressRoutes.

- fc-landing: Add Certificate, change tls: {} to tls.secretName
- fc-mysql: New app (Certificate + IngressRoute only)
- fc-php: New app (Certificate + IngressRoute only)
- fc-desktop: New app (Certificate + IngressRoute only)
- fc-signage: New app (Certificate + IngressRoute, plus HTTP route for players)

Deployments/Services for mysql/php/desktop/signage are managed by
deploy scripts, not ArgoCD. These apps only manage TLS + ingress.
