ProxMenux Notification Templates
Message templates for all event types with per-channel formatting.
Templates use Python str.format() variables:
{hostname}, {severity}, {category}, {reason}, {summary},
{previous}, {current}, {vmid}, {vmname}, {timestamp}, etc.
Optional AI enhancement enriches messages with context/suggestions.
