Three compounding bugs prevented language switching on the store dashboard:
- Cookie missing path="/", scoping it to the API endpoint path only
- STORE frontend resolution chain ignored the cookie entirely
- Store header used inline x-data with wrong language names instead of shared languageSelector()
Also updates architecture doc with correct per-frontend resolution priorities,
cookie name, API endpoint path, and file references.
