Extract the dashboard-layout optimistic-concurrency mechanism (issue #581)
into a shared server helper (takeBaseToken plus guardedUserUpdate /
guardedRowUpdate) and a client helper (readUpdatedAtToken, withBaseToken,
isConflict). Retrofit the dashboard-widgets route onto the helper and apply the
same guard to the insights layout, medications layout, and coach about-me write
endpoints.
A request that omits the base token keeps the byte-identical unconditional
write, so older clients are unaffected. Document the contract in the OpenAPI
registry, including the dashboard-widgets path that was previously absent.
The medications page gains a compact table beside the card view — one
row per medication with the same served-due status pill, next-intake
line, cadence-scaled adherence bars, dose-derived stock and the take
and skip actions the cards use, all from the payloads the cards
already read; the list response aggregates stock in the same round
trip. Columns sort tri-state with nulls last, the default order is
yours to arrange — the same drag dialog the dashboard and insights
use, applied to both views — and the chosen view and order persist
per user on their own settings column with field-scoped writes, so
toggling the view never touches the order. Inactive medications pin
to the end, the first column stays put under horizontal scroll, and
the loading skeleton follows the view you left.
