fix: линии графиков без цвета становились chart.js-дефолтом (не видно на тёмной теме) ...

- ChartLine: fallback — CHART_COLORS[0], watcher обновляет цвета серий
- сервисная страница: SERIES_MAIN #5BC795 (7.5:1 на #1E2522) + заливка

feat: upgrade to gnexus-ui-kit 1.0, adopt Verdant color theme ...

Kit 0.4.0 → 1.0.0 (git dep pinned to master): rounded panels, softer
accents, tabs as segment switcher, page-header scan animation removed
by the kit itself. Custom overrides dropped where the kit now handles
them (48px topbar brand).

Theme: kit-verdant.css import (exports map only whitelists kit.css in
1.0 — theme file resolved through a vite alias until the kit ships
theme exports). Chart palette rebuilt for Verdant and re-validated
(L 0.48–0.67, chroma, CVD, contrast on #1E2522). Logo/favicon
recolored to the Verdant hues. allow-git=git.gnexus.space in .npmrc
for npm 12 git dependencies.

feat: stage 3 — Vue web UI (dashboard, server page, charts) + docker build ...

Frontend (Vue 3 + Vite, gnexus-ui-kit, chart.js):
- login by admin token (localStorage, Bearer)
- dashboard: server cards with status, CPU/RAM/disk progress, net MB/s, note
- server page: metric cards, info (hostname/os/kernel/ips), editable note,
  history charts (1ч/6ч/24ч/7д), tabs: overview/disks/net/processes/docker
- create-server flow with one-time key display + install command

Backend: serve built SPA from panel/backend/static (assets mount + fallback)

Docker: multi-stage build (node:22 → npm ci/build → static into python image),
build context moved to repo root, .dockerignore added
