POS Cash Opening Adjustment

This module provides adjustments for the POS opening cash mechanism in Odoo 19.

Features

• Overrides _set_opening_control_data to properly initialize and track opening_cash_expected and opening_cash_counted while utilizing Odoo's native functionality.
• Tracks opening cash correctly so that the system correctly calculates differences.
• Leverages standard Odoo 19 journal handling for robust accounting integration.
• Suppresses positive cash differences automatically via standard backend validations, adjusting the cash_register_balance_end_real to match the expected balance when there is a surplus.

Technical Details

This module modifies the pos.session object, tracking:

• opening_cash_expected: The expected cash balance when opening the session.
• opening_cash_counted: The actual cash counted by the cashier.
• opening_cash_difference: Computed difference between counted and expected opening cash.

It modifies the standard _validate_session process strictly for suppressing positive discrepancies (where the ending cash register is higher than expected), logging the event into the chatter.
