The accounting report test suite was adjusted to match the standard payment and receipt accounts now created automatically with the chart of accounts. This prevents internal test conflicts and helps keep accounting-related updates reliable without changing day-to-day user workflows.

In this PR:
- As part of recent changes, the default Outstanding Payment/Receipts accounts are now always created when the Chart of Accounts is loaded, and several test cases were updated to avoid unique constraint errors.

- Previously, these test cases manually created accounts with codes like `OSTR00` and `OSTP00`. Now that these accounts are created by default, attempts to redefine them or change their codes have led to conflicts.

- This commit updates the affected test cases to:
  - Use the correct default account codes directly (101403, 101404)
  - Avoid reassignment of codes that are now created by the CoA template

Duplicating a salary attachment no longer carries over the amount already paid. This prevents copied records from inheriting case-specific payment history, helping payroll teams start each duplicate with accurate values.

This update replaces an outdated stock picking date with the record creation date in related delivery, subscription, and reporting logic. It improves the reliability of stock picking filters and reports, with upgrade support handled separately.

This change was suggested by a contributor, but it requires an upgrade
script, so a set of 3 new PRs was created. The original purpose was to
improve the stock picking filtering in `simulate_period` test helper
method. While working on this, it became apparent that the `date` field
in stock picking is useless and it should be replaced by `create_date`.

Payroll payment reports now use the clearer label “payment date,” and payslips are automatically updated with that date. US payslip layouts are simplified to show the payment date, hide less relevant employee details, and display only the last four digits of bank accounts for clearer employee communication.

When creating a payment report, the user must can choose the effective date. The term is ambiguous and is replaced by this commit by payment date. Additonnaly, the pay_date field on the payslip is automatically filled according to the payment date of the attached payment report.

Also, this PR improves the US payslip template to better follow best practices:
- The payment date is added
- The job position, department and worked days are hidden
- The phrasing of the bottom sentence has been changed and only the last four digits of the bank account are shown

Timesheet entries now rely directly on their linked project to determine timesheet behavior, instead of using a separate internal marker. This reduces duplicated logic and helps keep timesheet reporting, merging, and timer workflows more consistent.

- Previously, the `is_timesheet` field was set based on the project associated with the timesheet. In this commit, we removed the `is_timesheet` field and now manage the logic through `project_id`.

Appointment sharing links are now generated in one consistent place, reducing duplicate behavior across calendar, form, Kanban, and Gantt flows. Users get cleaner name-based links when possible, fewer duplicate invites, and more reliable link editing and creation.

Purpose:
The short_code generation mechanism is made central, such that Kanban, Form, and Gantt views' share invite's code duplication can be avoided.

Specifications:
1. Generate a unique link. 
   Case 1: Generate name based link when no link exists for the appointment eg. /schedule-a-demo. 
   Case 2: If a link exists for the appointment: Retrieve the existing link for the current configuration, or else generate a random code.
2. Avoid invite duplication on appointment duplication.
3. Change the button string from Cancel to Discard and short_code_unique_warning in view appointment_invite_view_form.
4. Remove AppointmentInviteViewFormController and associated files, as the same code is done on the server side to avoid code duplication.
5. Generate an appointment name-based link(if the link does not exist)for the appointment listed in the dropdown on the calendar side.
6. We can now alter the short_code of existing link and generate a new link.
7. Set default appointment type when we click on New btn in list view of links of the appointment.
8. Update the appointment name which is created via 'Share Calendar' click.
9. Test case has been created so above functional flow doesn't break.

Belgian payroll now places the ONSS CO2 fee before the employer ONSS contribution and includes it in that employer contribution total. This helps ensure payslip calculations and reporting better reflect the required treatment of company car CO2 fees.

The ONSS CO2 Fee must appear before the ONSS employer rule and included in its sum.

The Partner Ledger no longer shows debit and credit amounts on initial balance and total lines. This reduces confusion from large historical amounts that do not relate directly to the selected reporting period.

Users are sometimes confused because Debit and Credit can show quite high amounts not related to the present period because of the initial balance.
We hide these columns for the initial balances, and to remain consistent, for the totals as well in the partner ledger.
