Comprehensively renamed all "Preorder" domain types, services, controllers, models, enums, database contexts, routes, views, JS, localization resources, and documentation to "PreOrder" (PascalCase, capital "O"). Updated all references in backend, frontend, localization, and schema docs for consistency. No business logic changes; this is a naming and normalization refactor.
- Restructured documentation: added `docs/README.md` to each sub-project, moved LOGGING and SIGNALR docs into dedicated subfolders with their own `README.md`.
- Updated all cross-references to use new topic folder paths and canonical AyCode.Core doc locations.
- Updated `.csproj` files to auto-include all Markdown docs and project-level `README.md` files.
- Removed obsolete single-file docs, replaced with structured content in topic folders.
- Enforced AI Agent Protocol: session setup, output prefix, no-re-read, and mandatory `docs-check` skill after code changes.
- Added domain-critical reminders and navigation guidance to relevant `README.md` files.
Replaced hardcoded Debug paths in all .csproj files with $(Configuration) for AyCode and FruitBank DLL references, enabling correct DLL resolution for any build configuration. Switched appsettings.json connection string to use the FruitBank_PROD database. Added a null check for StockTaking in StockSignalREndpointServer.cs to prevent possible null reference exceptions. Noted some encoding issues in .csproj comments and copyright fields. No other functional changes.
