This fixes a visual layout issue in the kanban color picker caused by a styling change intended for the accounting dashboard. The accounting upload link keeps the intended appearance, while other dashboard popovers display correctly again.

This PR fixes an issue introduced in Commit[^1].
Prior to Commit[1], we were using the mixin `o-kanban-dashboard-dropdown-link` to handle the spacing of the link within the popover. This mixin was scoping this change to `<a/>` tags that are direct children.

Commit[1] was trying to change the color of the file upload link on the accounting dashboard to replicate the design of the other elements but instead of tweaking the `@include` on the Accouting side, it modified the `@mixin` directly, meaning this now affects all the links, color picker as well, resulting in a broken layout.

To fix this issue, we scope back the change to direct children while providing the desired result in the account dashboard.

This fix ensures dark mode styling files are only loaded when dark mode is used, instead of being included in the standard light mode view. It helps prevent visual inconsistencies in restaurant appointment planning screens that use Gantt views.

This commit fixes an asset issue with web_gantt where the dark mode specific assets from web_gantt were included in the main (light mode) assets from pos_restaurant_appointment.

The WhatsApp test coverage was updated to match recent shared platform changes around attachment handling, including voice attachments. This helps keep WhatsApp messaging behavior reliable and aligned with the latest expected workflows.

The Sign app now has the missing icon mapping needed to show the correct sidebar icons when new item types are used. This prevents errors and keeps the signing template setup experience working smoothly.

After #75291 we are using `icon_type` map to display the sidebar type icon if it's not defined on the item type. However the `icon_type` map wasn't defined anywhere which causes an error with new types.
