feat(polish): default tracking modules on; illness backdate + course fixes

A clean install now defaults every tracking module on (weight, blood
pressure, glucose, sleep, mood, medications, labs, documents, insights,
mental wellbeing, cycle, illness, environment, workouts) so the app is
usable without enabling each surface by hand. Only the two channels that
open an egress or attack surface stay opt-in — the remote MCP endpoint and
the micronutrient sync; the document AI-read and the daily-briefing push
remain separately gated and off. The change touches defaults only:
accounts with a saved preference resolve exactly as before, the new default
applies solely where no preference exists.

Drop the "typical range = median ± MAD" method caption from the vitals
baseline tiles — it repeated across every tile and read as out of place at
the top of the vitals surface. The dedicated bands and composite scores
keep their method copy.

Illness episodes: the capture sheet now carries an editable end date
alongside the start, so a whole past episode can be recorded after the
fact and an open-ended course can be resolved (or re-opened) later. The
end is bounded to on-or-after the start.

Fix the per-episode "how it progressed" card rendering an empty body when
the engine returned a valid result with no notable findings — it now shows
a calm, honest line instead of looking as though nothing was recorded.
