peter 9a3b381f39 Add light/dark mode toggle for the UI
The UI stylesheet already centralized its palette in a :root block, so this
mostly meant (1) migrating the ~30 colors still hardcoded in rules into
variables so they flip in one place, and (2) adding a [data-theme="dark"]
override palette. Artifact rendering is untouched — those use the separate
static/themes/*.css and the preview backdrop stays white by design, since
artifacts (charts, reports) are authored light.

- Toggle lives in the gear-menu dropdown (Dark mode / Light mode), persists
  to localStorage.
- A tiny inline script in each page <head> (feed, settings, login) applies
  the stored theme before first paint, so dark-mode users never see a white
  flash on load.
- color-scheme: dark on the dark palette makes native form controls
  (inputs, buttons) render dark too.
- Semantic accents (kept=green, shared=blue, today, danger) got
  dark-appropriate variants; status/data-viz colors (usage bar, tag chips)
  and the white artifact backdrop are intentionally left as-is.
