fix(theme): light-mode polish from review pass

Self-review of the light/dark sweep surfaced neutral colors that lived
in raw inline-style / <style jsx> / gradient values (so the className
sweep correctly skipped them) and a few contrast/affordance nits:

- reply-quote: adapt to the outbound (primary) bubble via onPrimary so
  the quote/author stay legible on the violet fill in light mode; wire
  it from message-bubble.
- dashboard SVG chrome -> tokens: conversations-chart gridline/crosshair,
  pipeline-donut background ring, automation-builder dot-grid gradient.
- members-tab viewer chip: bg-card -> bg-transparent (outline) so it
  doesn't blend into a card surface in light mode.
- tag-manager / pipeline-settings color-swatch selection rings: raw
  slate/white -> var(--popover)/var(--foreground) so they flip.
- pipeline-board scrollbar (<style jsx>): slate rgb -> var tokens.
- activity-feed zebra stripe: bg-card/40 -> bg-muted/40 (survives light).
- forgot-password / import-modal: restore real hover (dead no-op hovers).
- themed-toaster: gate theme via useSyncExternalStore to avoid a
  hydration mismatch on sonner's theme attribute (no setState-in-effect).
