feat(illness): clarify the condition-journal layout

Rework the illness list so each episode reads as a medication-styled card:
the header carries the label link, neutral type / status badges, and the
overflow kebab; a single bottom-pinned "Log a day" button is the one
explicit action per card. Drop the redundant chevron — the card title is
already the link.

Split the flat list into Active / Resolved groups (active first) and nest
flares under their parent condition so the parent relationship the form
captures becomes visible. Lift the retrospective summary above the list so a
long history no longer buries it.

Host the per-day timeline exclusively on the detail surface: the list rows
stay clean summaries, and navigating reveals today's logged symptoms,
functional impact, fever, and note alongside the correlation card. Neutral
palette and retrospective-only copy throughout.
