[measure-tools] Flip condition for measurements in sheets

[Maxime-Brassard]

We flipped the conditions for sheet measurements in order to make them work on models where these details are not provided.
Before, we'd allow using the measurement only inside drawings that were in the allowedDrawingTypes list. Now, instead, we prevent using the measurement inside drawings in the forbiddenDrawingTypes list and allow everywhere else. That way, we're able to use the measurements when the data is not populated and still prevent using the measurements where it does not make sense.

Pull request overview

This PR updates sheet-measurement validity logic to be denylist-based instead of allowlist-based, enabling measurements to work when sheet drawing-type metadata is missing while still blocking nonsensical contexts (e.g., Detail drawings).

Changes:

• Replace “allowed drawing types” checks with “forbidden drawing types” checks (tools now forbid Detail rather than only allowing a small set).
• Update SheetMeasurementHelper tooltip and drawing-type gatekeeping helpers to match the new denylist semantics.
• Adjust localized tooltip strings to say “cannot be used on …” and update list-joining wording accordingly.
