Lets staff set a friendly name for a device independent of whatever
name the end user gave it in the app. console_name is never shown to
app users and never synced from/to device_name; every display label
across search, equipment/helpdesk name resolution, device search, and
the Manage tab's issue linker now falls back through console_name ->
device_name -> serial rather than device_name alone.
Also includes an incidental one-line fix in devices/service.py: the
nested-struct deep-merge in update_device() was missing the newly
added device_health_settings key.

subscrStart, warrantyStart, and maintainedOn are written to Firestore as
Timestamps like the other date fields here, but were missing from
_TIMESTAMP_FIELD_NAMES, so they weren't being converted back to ISO
strings on read.

Two-tier (warning/critical) threshold config per device — restarts/week,
RSSI floor, free-heap floor, CPU temp ceiling, plus an offline timeout
used for both a client-computed health status icon and the Health tab
chart's gap detection. Purely advisory for now: no server-side
email/push alerting infra exists yet, so email_on_threshold and
push_on_crash_boot are placeholders for that future work.
