Hybrid Gen4 dry contact: align entities with the app's dependency tree

The dry-contact load-management family now mirrors the structure the
SolaX app presents, verified live on an X3-Hybrid-G4 15kW by changing
each setting in the app and tracking the readback registers
(write 0xB6-0xC2 -> readback 0x122-0x12E):

  Dry Contact Mode (0xC3): Generator Control / Load Management
    Load Management (0xC2): Disabled / Manual Mode / Smart Save
      Load Management Manual (0xB6): on/off switch
      Smart Save Threshold On Feed-in Power (0xB7, W)
      Smart Save Threshold Off Consumption (0xB9, W)
      Smart Save Threshold Off Battery SOC (0xBA, %)
      Smart Save Minimum Per On Signal (0xBB, min)
      Smart Save Maximum Per Day (0xBC, min)
      Smart Save Schedule (0xBD): enable/disable
        Smart Save Work Start/End Time 1 and 2 (0xBE-0xC1)

Renames only touch display names; keys and entity ids are unchanged.
The Work Mode select option "Manual" becomes "Manual Mode" (readback
scale updated in sync).

feedin_on_power, consume_off_power and the manual switch were missing
the DCB gate and appeared even when the dry-contact box option was
disabled; they are now gated like the rest of the family.

Switch On SOC (0xB8) appears in no app screen and never changed during
the live tracking session, so it is hidden by default until SolaX
documents its role.
