Outlook-specific table formatting suppression is persisted globally

[ChenZ2000]

Temporary Outlook table-formatting suppression is being persisted to NVDA settings.

In addon/appModules/outlook.py, the Outlook focus handler changes config.conf["documentFormatting"]["reportTableHeaders"] and reportTableCellCoords when focus enters the Outlook grid.

That makes an Outlook-only suppression leak into nvda.ini or the active profile when the user saves settings or exits NVDA.

Expected:
Any suppression here should stay Outlook-only and runtime-only.

Actual:
Focusing the Outlook grid can permanently change the user's global table header / cell coordinate settings.

I first tried the minimum possible fix: removing the two writes to config.conf["documentFormatting"] in the Outlook focus handler.

That did stop the persistence bug, but it also removed the current Outlook-specific suppression behavior.

A tested better approach is:

• apply the suppression only while Outlook is active
• restore the user's real settings on app lose focus
• restore the user's real settings before config save / reset
• re-apply the suppression after save only if Outlook is still active

This keeps the current Outlook behavior while preventing nvda.ini or profile pollution.
