feat(medications,coach,admin,perf): era corrections, a truthful weekly status and one card language everywhere

The dashboard snapshot fires the moment login succeeds instead of
waiting for the page chunk (start ~670 to ~200 ms throttled). Guided
follow-ups are personalised from the user's snapshot and an answer gets
the coach's streamed reaction before the next question. Archived
schedule eras can be corrected through a superseding revision that
keeps the original as an audit trail, era writes serialise per
medication, and duplicate dose times collapse in validation. A rolling
medication whose next dose is tomorrow can no longer read as heavily
overdue — the card status derives strictly from the served next-due —
and the adherence bars keep a fixed geometry in every state. The
server-wide assistant key gains its admin card, the one duplicated
coach preference collapses onto a single owner, twenty-seven admin and
settings card headers move onto the shared pattern with sixty
containers normalised, and the remaining hydration warnings are gone.
