feat(mobile): mobile cards for reminders, audit log, users

Three new <EntityCard> files using the shared <ListCard> shell, wired
into each list page's <DataTable> via cardRender.

  - ReminderCard:   Bell icon, related-entity subtitle (User/Anchor/
                    FileText icon by entity type), due-date meta with
                    past-due flag, accent bar (rose=past-due,
                    amber=pending, slate=snoozed, emerald=done).
                    Snooze/Complete/Edit/Delete in actions menu.
  - AuditLogCard:   Action icon (Plus/Pencil/Trash2/Eye), entity
                    title, "{verb} by {actor}" subtitle, timestamp
                    meta, optional changed-field chip line. Accent
                    bar by action (created=emerald, updated=blue,
                    deleted=rose). Immutable, no actions menu.
  - UserCard:       Initials avatar, displayName/email, role meta
                    (Shield icon), last-login distance, "Inactive"
                    pill when deactivated. Accent bar (violet=
                    super_admin, slate=inactive, none=active).
