fix(insights): MED-bucket polish across coach + report surfaces

- weekly-report eyebrow chip drops uppercase + tracking-wide for the
  sentence-case rule the rest of the app follows; print stylesheet
  now neutralises bg + colour so monochrome output reads clean
  (Design-M4, Design-L3).

- correlation-card "Try a 7-day experiment" CTA flips from default to
  outline while disabled. Disabled-primary read as "the system is
  broken right now"; outline reads as "this is on the roadmap"
  (Design-M7).

- coach-drawer settings cog aria-label switches to the coming-soon
  tooltip copy so SR users hear the same "arrives in v1.4.21" message
  sighted users see (Design-M9).

- sources-rail static "fresh" dot becomes aria-hidden — v1.4.20 has
  no real freshness state behind it; SR users no longer hear "Fresh"
  five times in a row (Design-L4).

- summariseTitle slices on Unicode code points rather than UTF-16
  code units so a user message ending mid-emoji ("🩺") no longer
  produces a half-character on disk (Code-LOW-04).
