This update reduces overhead in Odoo's internal caching logic, especially in areas used when preparing website and template assets. It should make some very frequent background operations faster without changing user-facing workflows.

`decorator` turns out to be quite heavy, if the decorated function is very fast (possibly since 5.0 and the switch to `Signature` as ~98% of the per-call overhead is spent in `inspect`).

Might be worth bypassing it in some cases. Alternatively surgically switching some decorators to `decoratorx` (introduced in 5.1 as the pre-5.0 behaviour via exec) might be a simpler and less disruptive alternative, if we didn't suffer from major decorator-related issues before the Signature stuff.

The web upload service documentation now makes clear that it can accept either a browser file list or a standard list of files. This helps teams prepare and filter files before uploading, such as excluding files that are too large, without changing user-facing behavior.

As the upload service (js) only uses iteration, index based access and length on the files parameter, it is compatible as well with an array of File as files parameter (instead of a FileList). So, we have updated the files parameter docstring to accept as well array of File. With this change we can easily pass a modified list of files (ListFile being hard to create on some browser). Example of use-case, only send to the upload service the files smaller than a given threshold by transforming a FileList to an array and then by filtering it.

Marc Demo no longer has administrator-level access in the Timesheets and Project demo data. This restores his previous, more limited permissions so teams can more accurately test access rights in Services-related workflows.

Since 16.0, the demo user Marc Demo has gained admin access to all the apps.
To facilitate testing access rights, this commit restores his access rights as they were before for the Services apps.

The CRM lost lead action now keeps its intended settings when opened from a list view. This ensures the modal window displays at the correct size, improving consistency for users without changing core CRM workflows.

Prior to this all of the context of the action called in the list action was overriden. We now combine the action context with the environment context.

For now, it just insures that the modal window opens with the correct size.

Decreases the space after o_Message_headerDate

Message action buttons in the Mail app now appear within the message area instead of floating separately. This makes message controls easier to find and gives conversations a cleaner, more consistent layout.

Improves the MessageActionList design to move the action buttons in the same
space as the message.

This PR is an alternative to [that PR](https://github.com/odoo/odoo/pull/90167)

This PR does:
    - Put the actionList Container in the same line as the header of an
          un-squashed message
    - Put a blank line on top of each squashed text message
          to put the actionList Container in.
