fix: store menu 404, logger crash, platform detection, and sidebar UX

- Fix store menu API URL (/store/menu/render/store, not /store/core/...)
- Fix storeLog/merchantLog fallback to console object instead of console.log
- Embed platform_id/platform_code in store JWT from URL context at login
- Use token_platform_id in store menu endpoint with DB fallback for old tokens
- Add "Menu unavailable" warning in sidebar fallback for all three frontends
- Standardize admin section default to all-open (consistent with store/merchant)
