chore(release): v1.28.3 — consistent spacing and alignment

A layout-audit-driven consistency pass: one shared left edge for insight cards
(headings and body align, worst on mobile), no scroll past content on settings
and admin pages, Settings/Notifications only in the account menu on mobile, the
dashboard action beside its greeting text, and preventive-care/cycle/onboarding
cards on the shared card anatomy. The spacing and alignment rules are recorded
in the standards. Also stages the document rasterization native binding in the
image so a scanned PDF is read on an image-only AI provider.
