wmantly 43349579e1 feat(wireguard): WireGuard peer manager UI — QR codes, .conf download, per-client exit node selection (#42)
* feat(wireguard): WireGuard peer manager UI with QR, .conf download, and per-client exit node selection

- models/wg_peer.js     — Redis-backed peer store with auto IP allocation (10.100.0.x)
- models/wg_site.js     — Redis-backed exit node store (admin-managed sites)
- utils/wg_keys.js      — X25519 keypair gen via Node crypto (no wg binary needed)
- utils/wg_conf.js      — client wg0.conf renderer
- routes/wireguard.js   — REST API: CRUD sites/peers, GET /conf, GET /qr (QRCode PNG)
- views/wireguard.ejs   — full dark-mode UI: exit node table, peer table, QR modal,
                           .conf download, exit node picker per client
- conf/base.js          — conf.wireguard block (serverPublicKey, serverEndpoint, dns, poolBase)
- Nav: WireGuard link added (admin-gated)
- No wg binary dep in Node process — key gen is pure JS X25519

* fix(test): update test script to run unit tests without native bcrypt binary dependency in CI

* fix(ui): replace native browser alert/confirm with app.messages in WireGuard view
