This update fixes a critical issue in Australian payroll calculations by ensuring tax and deduction figures accurately reflect the pay period's historical settings. Previously, the system used current employee data, leading to incorrect calculations when employee details changed. Now, payrolls use the correct historical data for accurate tax and deduction processing.

Since the introduction of the employee versioning system, using `employee.field_name` in salary rules is no longer accurate for computations involving historical or specific periods. Accessing fields directly on the `employee` record returns the current values.

This creates an issue when a future version exists. For example, if a new version is created for February 2026 with an updated Child Support amount, generating a delayed payslip for January 2026 would incorrectly use the February value (current state) instead of the January value (historical state).

This commit updates the Python compute logic in the Australian salary rules to use `version.field_name` instead of `employee.field_name`. The `version` object ensures the data used corresponds strictly to the payslip's period.

The following rules/fields are updated to use the version object:
- Tax Treatment Category
- Additional Withholding Amount
- Extra Pay
- TFN Declaration
- Medicare (Reduction, Exemption, and Levy)
- Training Loans
- NAT 3093 Amount (Tax Offset)
- Child Support (Garnishee and Deduction)

A test case is added to verify that a payslip correctly retrieves the child support amount from the version valid during the payslip period, ignoring future updates.

This update resolves a technical issue that prevented emails from being sent correctly when processing multiple equity transactions. The fix corrects a configuration error in the email template, ensuring accurate record matching and preventing errors during email generation. This improves the reliability of equity transaction email notifications.

## Issue Before This Commit

A missing record error occurred during email generation when the number of
`equity.transaction` records exceeded the `res.partner` records.

## Cause of the Issue

The issue was caused by an incorrect `model_id` configuration in the
`equity_shareholder_email_template`. This created a mismatch between the
template model and the record context passed to the mail compose wizard,
leading to a missing record error during template rendering.

## With This Commit

The template `model_id` has been corrected `equity.transaction`. This ensures that the 
mail compose wizard receives
the correct model context and prevents missing record errors during
email generation.
