test: fix Galaxy-tag Phase7 test fixtures + S7 CLI enum; add MaterialiseGalaxyTags coverage

Completes the test side of the in-progress Galaxy-tag workstream:
- Phase7ApplierTests / Phase7ApplierHierarchyTests: supply the now-required
  Galaxy-tag args to Phase7Plan / Phase7CompositionResult.
- Add genuine coverage for Phase7Applier.MaterialiseGalaxyTags (folder-per-distinct-path,
  variable-per-tag node-id derivation, folder dedupe) + added-Galaxy-tags-trigger-rebuild.
- S7.Cli.Tests: use the project's S7CpuType (CLI option type) instead of S7.Net.CpuType.
Whole solution now builds 0/0; OpcUaServer.Tests 52, S7.Cli.Tests 36 green.
