Fix: Fragile service name parsing in applyServiceApplicationPrerequisites

Changed from `->before('-')` to `->beforeLast('-')` to correctly parse service
names with hyphens. This fixes prerequisite application for ~230+ services
containing hyphens in their template names (e.g., docker-registry,
elasticsearch-with-kibana).

Added comprehensive test coverage for hyphenated service names and fixed
existing tests to use realistic CUID2 UUID format. All unit tests pass.
