ZMB Webui: Complete Project – Rebrand & Initial Clean Commit

ARCHITECTURE
============
Backend: FastAPI + uvicorn (port 8000)
  - JWT authentication with PAM system users
  - ZFS CLI wrapper with caching (30-60s TTL)
  - WebSocket pool status broadcaster (30s interval)
  - Services: auth, zfs_runner, file_manager, shares, identities, system_info
  - Routers: pools, datasets, snapshots, shares, identities, navigator, system

Frontend: Next.js 15 + TypeScript (static export)
  - Incremental Static Regeneration (ISR) for weak hardware
  - Type-safe API client (lib/api.ts)
  - Dark mode + custom Tailwind theme
  - Pages: Dashboard, Login, Snapshots, Datasets, Shares, etc.

DEPLOYMENT
==========
Test Target: 192.168.1.179:8090 (Debian LXC)
Production: 10.66.120.3:9090 (Raspberry Pi 4GB ARM64)
Updater: Automated Gitea-based deployment (update-test.sh, update-pi.sh)

FEATURES COMPLETED
==================
Phase 3a: Dashboard Quick Stats (System, CPU, Memory, Storage)
  - Real-time stats with color-coded progress bars
  - Responsive grid layout (mobile: 1, tablet: 2, desktop: 4 columns)
  - ISR-optimized for fast loads on weak hardware

REBRANDING
==========
Renamed throughout:
  - Project: 'ZFS Manager' → 'ZMB Webui'
  - Services: 'zfs-manager' → 'zmb-webui'
  - Systemd units: zfs-manager-backend → zmb-webui-backend
  - Configuration files and documentation
