Inventory-related screens were adjusted so fields take up space more consistently and layouts look cleaner. Several labels now use the shorter “UoM” wording instead of “Unit of Measure,” making views easier to scan for users.

Before this commit some fields were taking extra space and ruining the UI by breaking uniformity as well as Unit of Measure is used in UI at different views.
After this commit uniformity was restored in UI and Unit of Measures was replaced by UoM in the several views of inventory.

Website menu setup now automatically includes the website designer access group when menus are restricted to specific groups. This reduces manual configuration and helps keep access rules consistent for website administrators.

Simplify the creation of `website.menu` records.  If a record has groups, then the group `website.group_website_designer` is added, too.

The default payment reminder email has been refined to make follow-up messages clearer and more polished for customers. The template also uses email-compatible styling so reminders display more reliably across email clients.

This commit slightly improves the default followup email message for payment reminder.

Payroll will no longer show a payslip duration warning when the selected salary structure is not configured to use worked day lines. This reduces confusing alerts for payroll teams in setups where that warning is not relevant.

If a structure has the setting 'use_worked_day_lines' set to False, we shouldn't
 show the warning for the payslip duration.
