Subject: [PATCH 1/2] fix(day): run only records with a start of their own
through a day
The "Running that day" list carried the profile facts (smoking status,
alcohol pattern, shift schedule) as running items, titled by their raw
codes and counted "day n" from the date the fact was filed. A person who
quit smoking years ago and entered it last week read "day 13". Those facts
describe the person, hold no start the person gave, and are not part of a
day; the lifestyle section and its running kind are gone from the day, its
index and the model-facing get_day.
The same false count reached a medication filed without a start date: its
creation date stood in as the start. `since` is now null there, with no
day count, and the entry's date only bounds which days show it. A life
event's category is worded in the reader's language instead of its code.

Subject: [PATCH 2/2] feat(day): collapse the docked day to an edge instead of
closing it
From 1280 px the day sits beside the page, and its control at the top
left took it away entirely: after a page change there was no way back to
the day short of finding it again. The control now hides the day the way
a sidebar collapses. A narrow edge stays on the right, holding the date,
with a button that opens the last day again on this page or any other.
Focus lands on that button when the day collapses and on the day's
heading when it comes back.
The last open day is remembered per browser, bound to the account and
the record it was read in, and removed at every session end. The Coach
button keeps clear of the edge as it does of the open day. Sheets below
1280 px and on phones close as before, and Back still closes them.

+ * The last day the layer showed, per browser, so the docked day can be shut
+ * to a narrow edge and brought back on another page (v1.42).
+ *
+ * A convenience, not a record: it lives in `localStorage`, every read and
+ * write is wrapped because storage can throw (private windows, blocked site
+ * data), and an unreadable store means "nothing remembered". The value is
+ * bound to the account and the record it was read in (`owner`), so another
+ * account on the same browser, or the same person reading a shared record,
+ * never gets it back; a session end removes it outright
+ * (`clearCachesForSessionEnd`).
+ *
+ * Client-only and free of Zod and server imports, like `contract.ts`.
