Website and portal errors now appear in clearer, more consistent dialogs, notifications, and error pages instead of plain technical pages or browser alerts. This improves the customer-facing experience when something goes wrong and makes permission or validation issues easier to understand.

All rpc errors are now displayed using the notification system recently
updated for website. For the redirections triggering an error that are
currently displayed as a 500 Error with an ugly white page, the error
page will be similar to 404/403 error but with code 400. All
exception_orm are now handled as a 400 except for the AccessError
which is a 403.

The error card on all the Error pages is now loaded on an open state
displaying clearly the reason of the error without clicking anything.
If there is no error message the error card is not displayed and the
traceback is open. The traceback is only displayed if we are in debug
mode. These changes are also effective for the 500, 404 and 403 error
pages.

KarmaError is now an except_orm exception.
Karma error message now contains the required karma.
All the alerts in website_forum will use the toast notifications
instead of alerts.

A test tour is located in test_website, visit /test_error_view to
trigger some errors manually and look at the result.

This update simplifies project forecasting by removing unused options and streamlining how forecast actions and recurring forecast creation work. It also keeps rental-related email date formatting aligned with shared system tools, reducing maintenance effort without expected functional changes.

Belgian payroll now supports managing wage garnishments such as salary attachments, salary assignments, and child support directly on employee contracts. These amounts are automatically included in payslip calculations and reports, helping payroll teams track deductions and amounts already paid.

Accounting report date and comparison filters now show warnings through the updated error dialog system. This gives users clearer feedback when required fields are left empty, especially in mobile workflows.

to test this feature: install account_reports, go to
Accounting > Reporting > Balance Sheet
Click on the date button "As of [date]" then custom
empty the field and apply. A warning should appear.
Same with the button Comparison next to it.
