The Enterprise web module now points each replaced web asset to the matching Enterprise version. This keeps the asset configuration consistent after the migration, with no expected visible change for users.

Replace each web file with the corresponding one in web_enterprise

Employees can now be moved from full-time to part-time on the same start date as their current contract without triggering an incorrect validation error. The system will handle this transition by closing the existing full-time contract, reducing administrative blockers for Belgian payroll users.

When changing a contract to part time, a validation error occurs when
the start date of the part time contract is the same as the running
contract. This behaviour should be possible, and when this happens we
will now close the cancel the full time contract.

Timesheets now treat approved time off as leave instead of counting it as extra worked hours. This prevents inflated overtime figures and gives managers and employees a more accurate view of work time during absences.

Currently in master, while an employee is on leave, the timesheet app
considers it as overtime and due to that, it shows extra worked hours.
In actuality, the employee was on leave.

So in this commit, When employees put leaves than the Timesheet
consider it as leaves rather than overtime.
