refactor(dry-F2): centralize shared UI primitives (relative-time, toast, download-status)
- utils/date.js: add formatRelative(iso, {future,nullText}); migrate 6 sites
(SourceRow, SubscriptionsTab, SourceHealthDot, SchedulerStatusBar +
thin adapters in BackupRunsTable/SystemActivityTab for their '—' null text).
PostCard (30d->absolute) and CredentialCard (mo/y buckets) intentionally
keep bespoke formatters.
- utils/toast.js: toast(opts) wraps the globalThis.window?.__fcToast?.(...)
incantation; migrate 63 call sites across 24 files.
- utils/downloadStatus.js: single source for the download-event status enum
-> label/color/icon; collapse the 3 duplicate maps (DownloadStatChips,
DownloadsFilterPopover, DownloadEventRow).
Net -33 lines. Platform metadata was already centralized in platformColor.js.
