Initial commit: ArchiTools modular dashboard platform

Complete Next.js 16 application with 13 fully implemented modules:
Email Signature, Word XML Generator, Registratura, Dashboard,
Tag Manager, IT Inventory, Address Book, Password Vault,
Mini Utilities, Prompt Generator, Digital Signatures,
Word Templates, and AI Chat.

Includes core platform systems (module registry, feature flags,
storage abstraction, i18n, theming, auth stub, tagging),
16 technical documentation files, Docker deployment config,
and legacy HTML tool reference.
