v1.2.0 — inverter run-state enum

Adds sensor.<device>_status — inverter run state as an enum (off / normal / sleep).

The connectivity binary sensor is on only when the device reports status 1, which collapses sleep into off — an inverter that legitimately sleeps overnight read identically to one that had dropped offline. Values match the legacy hinen_power semantics (0/1/2) and the entity ID matches the one it used, so prior dashboard references bind straight back.

Additive only — no existing entity IDs, unique IDs or names change.

⚠️ Still includes the v1.1.0 breaking change: Work Mode option values are stable slugs (self_consumption, battery_priority, grid_priority, time_period, power_keeping), not display labels.
