Subject: [PATCH] Centralize BaseUrl logic via AcEnv; enforce fail-fast

Refactored BaseUrl handling so FruitBankConstClient delegates all access to AcEnv.BaseUrl in AyCode.Core, ensuring a single source of truth and fail-fast validation. Removed redundant _baseUrl field and logic from FruitBankConstClient. Updated startup files to hydrate BaseUrl from configuration and improved comments to clarify the new delegation and configuration conventions.
