Subject: [PATCH] feat(deploy): enable pcscd on upboard (sintra/tejo) for NFC
 gate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The access gate (ADR-003, #86) only wired services.pcscd + the pcsc
polkit rule into batm3.nix, so the tap-to-enter reader was invisible on
upboard machines. Port the same device-agnostic wiring to upboard.nix
(HID Global OMNIKEY 5022, 076b:5022) so the gate works on the sintra dev
unit — and on tejo — when #86 lands on dev and the nightly upgrade pulls
it.
