Email attachments are now handled with separate displays for image previews and regular files. This makes attachment areas easier to maintain and should provide a more consistent experience when viewing or managing files in Odoo messages.

Current implementation switch display between file attachment and image
attachment. This commit split those behaviour in 2 components.

This update continues the revamp of subcontracting workflows to make manufacturing operations easier to manage and more reliable. Businesses using subcontracting should see a more consistent experience when coordinating outsourced production activities.

The barcode reception info view now only shows the Allocation button when there are items that can actually be allocated. It also saves current work before opening allocation-related screens, helping prevent users from losing changes during warehouse receiving workflows.

Small fix/improvement:

1. Make "Allocation" button show in "i" form view only when moves to allocate to. (i.e. match community behavior)
2. Commit changes when "i" button is clicked on. This is due to "Allocation" button opening a "new" window when opening the action. After OWL-ification, the default behavior when this occurs is to wipe any not committed changes. Obviously we do not want to lose our work when clicking on this button.

The mail enterprise module updates its automated checks for attachments to match a newer interface component. This helps keep quality assurance aligned with the current product behavior without changing the user-facing attachment experience.
