Add VELA-values.yaml overrides for all monitoring ArgoCD apps

Each Helm-based app now loads a VELA-values.yaml file after the base
values.yaml, providing a dedicated place for environment-specific
config (ingress, storage class, node selectors, image overrides, etc.)
without editing the shared defaults.

Mosquitto and bridge apps converted from single-source to multi-source
ArgoCD Applications to support the additional values file reference.
