Improved Imports, And Fixed Scheduling

Added background image configuration for membership activation flow pages.

Added an auto_tax_disabled partner setting so partners can opt out of automatic tax collection.

Improved secondary partner imports so new sites can be associated with existing clients without creating duplicate client records.

Improved the mobile conversations side panel so focusing autocomplete fields no longer triggers disruptive browser zoom.

Improved partner account access by allowing internal users to reach non-BPO partners through a dedicated user-group exception while keeping those partners hidden from the normal picker.

Fixed Smart Send scheduled replies so the selected send time is preserved after saving.

Fixed missing labels in Rules Engine conditions so existing labels appear reliably when configuring rule logic.

Fixed an address update reliability issue that could cause requests to fail under load.

Fixed automated revenue sharing billing so partners using automated revenue sharing no longer get partner invoice items added through the standard billing path.
