feat(installer): Licora v5.1.0 Smart Installer & First-Run Wizard

Licora v5.1.0 — Smart Installer & First-Run Wizard

Summary

This pull request implements Phase 2 of the Licora Development Roadmap.

It adds a professional first-run installation wizard while preserving the frozen v5.0.1 baseline compatibility contract and all v5.0.1.1 security behavior.

The installer is an independent compatibility wrapper around the existing installation process. It does not modify Licora business logic, license generation, license validation, API contracts, database schema, admin routes, cron behavior, or frontend assets.
