Summary

When opening the add form (a) or editing an entire row (pressing Enter on the ID column), the inactive tabs in the tab bar are not rendered with strikethrough styling. They should be struck through to indicate they are not interactive during form entry, consistent with other modal states.

Steps to reproduce

1. Open any tab (e.g., Projects)
2. Press a to add a new item, or select a row and press Enter on the ID column to edit
3. Observe the tab bar -- inactive tabs appear in their normal style instead of struck through
