Migrations 030 (sites), 032 (device_interfaces), 033 (wireless_links),
and 034 (sectors) were missing GRANT statements for app_user and
poller_user. Without these, fresh deploys crash on site/sector CRUD
with permission denied errors. Also added poller_user SELECT grants
to migration 035 (site_alert_rules/events).

- WirelessLink model with LinkState enum (discovered/active/degraded/down/stale)
- Register DeviceInterface, WirelessLink, LinkState in models __init__
