refactor: derive compare-service resource types from dependency graph and resource-path libs

Replace hardcoded resource type lists with derivations from the same
model used by extract and publish:

- TOP_LEVEL_TYPES = TIER_1 + TIER_2 + non-child TIER_3 (mirrors extract-service)
- getChildTypesOf(parent) uses getDependencies() from dependency-graph.ts
  so newly added resource types are automatically included
- TYPE_OPTIONS map centralises per-type skip/exclude flags
- RESOURCE_TYPE_LABEL map centralises display labels with enum-name fallback
- McpServer now automatically included as an API child (was previously missing)
