feat: goddess sync, sanitize, and apotheosis init (chunk 3)

- initialState: add initialGoddessState() with all goddess sub-objects
- apotheosis: init GoddessState on first apotheosis, preserve on subsequent
- game: add goddessSpread block in validateAndSanitize (server-only fields capped, forward-only boss/quest/achievement enforcement)
- debug: add injectMissingGoddessExplorationAreas helper and inject all 8 goddess content arrays in syncNewContent
- vitest.config.ts: remove 8 goddess data files from coverage exclude (now imported via initialState)
- tests: full coverage for all new code (482 tests, 100% coverage)
