fix(ui): polish the light palette, center the stage bloom (#108)

* fix(ui): make the light theme a real light theme

The web shell hardcoded dark surfaces (panel hex, white/black alphas,
white text), so switching to light left the sidebar, chat, composer and
side panel dark with ink text on top. Shell surfaces now use the shared
tokens: light gets a warm paper frame with white panels, hairline borders
and short soft shadows; dark keeps its look via dark: variants.

- Light palette: visible borders (border was equal to muted), white
  primary-foreground, lighter user bubble, readable warning/success.
- Selected sidebar row lives in one place (roster-row-style).
- Markdown, inline code, code blocks, quotes and scrollbars follow tokens.
- cn() now knows the text-ui-* scale is a font size; tailwind-merge
  treated it as a color and dropped labels' color on resized buttons
  (sign-up submit rendered ink on ink).
- Stage bloom was offset left by a double translateX.

* refactor(ui-web): leave the cn() fix to #115

#115 fixes the same tailwind-merge bug more completely (text, control,
icon and spacing scales, guarded against styles.css) and adds the same
two files, so this branch drops its narrower copy to avoid the overlap.
