Add device config for Lidl Tronic Solarstromspeicher (Marstek Saturn B2500) (#5457)

- Battery storage device, Tuya category bxsdy, product id fpi7g58s9hoxlvng
- Sensors for battery %, charge/discharge power/current/voltage (DP 3),
  PV1/PV2 input (DP 101, daytime only), DC output OUT1/OUT2 (DP 33),
  lifetime energy counters (DP 37/102/103/104)
- Controls: operating mode select (DP 105), temperature unit select (DP 24),
  inverter output power limit (DP 115), discharge power slot 1 (DP 106,
  masked base64 write), depth of discharge (DP 107)
- Diagnostics: fault code, pack count, standby threshold, inverter max
  power (decoded from DP 114), force-refresh button (DP 111)
- Reset button for DP 106 slot 1 initialization after reconnect/restart,
  since the device never pushes DP 106 on its own and masked writes fail
  with 'Cannot mask unknown current value' until the first full blob write
- Uses existing translation_key entries where a good match already
  exists (power_x/voltage_x/current_x, energy_produced, energy_consumed,
  time_remaining, temperature_unit, status); no new translation keys or
  translations/en.json changes, per maintainer feedback to keep new
  device configs and translation additions in separate PRs

Tested against a real device for several weeks.
