Refactor web UI: feature-first structure, tokenized styles, modern blue theme.

Structure
- pages/ -> features/<domain>/{Page, components, hooks, lib}; 95 files moved,
  333 imports rewritten, verified with tsc.
- services/api.ts -> services/api/<domain>.ts (250 exports preserved),
  types.ts -> types/<domain>.ts, i18n zh/en -> locales/<lang>/<namespace>.ts
  (2696 messages deep-equal before/after).
- ESLint rule: shared layers must not import features/.

Styles
- index.css (16k lines) split losslessly into styles/{base,layout,components,
  pages,legacy,theme}; compiled CSS was byte-identical before tokenizing.
- ~930 hard-coded colors replaced by --nx-* tokens (theme/tokens.css); WebCRT
  off-palette colors unified; fixed dark-on-dark text introduced by mapping.
- theme/theme.css: modern blue design language (rounded shapes, gradients,
  unified buttons/fields/tables/modals), form-grid alignment fix, flat nav list
  without tree indent, soft selected state instead of left accent bar.

Docs: WEB.md documents code structure and style rules.
Not touched: the large Biz*/Webcrt/Topology page components (to be split later).
