Undocumented G_WorkingMode value "Power Distribution" causes sensor to be unavailable

[bobbesnl]

Describe the bug

During testing of PR #42/#44/#45 on development, the connected THOR (charger ID XGJ00003214700CA, firmware THOR_22AS-V2.2.16-20240902) returned G_WorkingMode = "Power Distribution" via GetConfiguration.

This value is not present in the alias map in configuration.py (_CONFIGURATION_ENTITY_ALIASES["G_WorkingMode"]), which currently only recognizes Fast/FastMode, PVlink/PVLinkage, and OffPeak/OffPeakMode. As designed, this results in:

• known: true, raw value preserved correctly in diagnostics (sensor.growatt_thor_ev_charger_working_mode diagnostics entry shows "value": "Power Distribution", "enum_label": null)

• The Working Mode sensor itself (sensor.growatt_thor_ev_charger_working_mode) correctly becomes unavailable, per the intended behavior that unmapped enum values should not be guessed

This is not a bug — it's the intended "fail safe to diagnostics" behavior. Opening this issue to track adding "Power Distribution" as a fourth recognized G_WorkingMode value once its meaning/relationship to the documented Fast/PV Linkage/Off-Peak modes is confirmed (possibly a fourth Growatt working mode, or a firmware/model variant naming difference).

Next steps:

• Confirm via Growatt app/web UI or further captures what "Power Distribution" corresponds to on this charger model

• If confirmed as a distinct mode, add it to CONFIGURATION_ENTITY_OPTIONS["G_WorkingMode"] and _CONFIGURATION_ENTITY_ALIASES["G_WorkingMode"] in configuration.py, plus corresponding translations in en.json/de.json/nl.json

• Update reverse_engineering/thor_22as_capture_findings.md with this observed valueIssue aanmaken in bobbesnl/growatt_thor met titel "Undocumented G_WorkingMode value "Power Distribution" causes sensor to be unavailable"?

"Additional observation from the same test session: the session-level workmode field in currentrecord also returned an undocumented value (7) for a session recorded while G_WorkingMode was "Power Distribution". sensor.growatt_thor_ev_charger_last_session_work_mode correctly displays the raw 7 (this sensor has no alias filtering, unlike the G_WorkingMode configuration sensor).

These two fields are distinct (charger-level G_WorkingMode string vs. session-level workmode integer code), but given they were observed together, workmode=7 may correspond to the same underlying charger mode as G_WorkingMode="Power Distribution". Worth investigating together when confirming the meaning of "Power Distribution"."
