Import UniFi Protect live views + optional auto-resync

views ls/dump/import copy a Protect live view (cameras + grid) into a
layout; grid inferred from slot count (asymmetric presets TBD, see
views dump). Imported layouts link back via protect_view.

Daemon re-syncs the active linked view every view_refresh_seconds (0=
off), so Protect-side edits appear on the wall. Needs the controller
password at runtime; off by default keeps the wall credential-free.

Shared viewmap package used by CLI and daemon.
