estimateRunDuration() computes a per-run ETA from a target count, a
fire time, and an assumed per-account send rate (40/min, mirroring
the bot env). Adds a 15% buffer with a 1-minute floor. Pure helper,
covered by 6 round-trip tests including the rate-defaults path.
Header CTA buttons on /accounts and /reminders are now size="lg"
rounded-full pills with a shadow that lifts on hover. Mobile shows
just the plus icon (label collapses) so the button doesn't dominate
narrow screens.
