DB: bazénové čerpadlo přes Shelly relé (V085)

- ems.asset_pool_pump (endpoint http, rated_power_w, min_run_min,
  daily_runtime_min jako aktuální sezónní hodnota, schedulable)
- ems.telemetry_pool_pump — 1min hypertable (is_on, power_w, energy_wh_total)
- signal_def POOL_PUMP_ON (bool) pro ovládání přes signal infrastrukturu
- fn_telemetry_pool_pump_sample (R__092), vw_asset_pool_pump_http_poll (R__093)
- fn_signal_enqueue_bool (R__094) — SQL-first zařazení bool signálu do fronty
