New /provisionDect slash command manages DECT basestations and handsets
for a store via a single card: multi-select checkbox list doubles as
the display, MACs render as AA:BB:CC:DD:EE:FF, Add/Remove sit
side-by-side per section, and every removal goes through an explicit
confirm card. Handsets always auto-pair (no bind-to-basestation input)
so they roam.
/finalizeStore now idempotently creates the "Store XXXX" DECT network
(DBS-210) with the per-store default access code, so new stores are
DECT-ready the moment finalize completes. Location-scoped lookup
(findDectNetworkInLocation) handles both the finalize idempotency
check and the /provisionDect fallback for freshly-created empty
networks. Non-critical: a store can still go live if the DECT step
fails, and /provisionDect keeps a recovery "create network" prompt
for legacy stores.
Pure-logic helpers (generateDectAccessCode, MAC normalize/format/
display, dectNetworkName) are unit-tested via node:test.
