feat(deployments): surface /deploy on the mobile nav + dashboard header

Capture entry-point was hidden in /tools cards.  Field workflow needs
to be one tap from anywhere, especially on mobile.

Mobile bottom nav: swap Devices → Deploy (slot 3).
  Menu / Dashboard / Deploy / Events.
  Devices still in the hamburger Menu drawer.

Desktop dashboard header: new orange "Field Deploy" button next to
"Last updated".  Only renders at md+ breakpoint (mobile already has it
in the bottom nav).
