Page section w/ table layout: fix flag column

[distantnative]

Description

Summary of changes

• Adds page status data both as button (for cards, card lets and let) and as separate flag entry (for table layout)
• Fixes [v5] Table layout: page status flag missing #6866

Reasoning

It's not the prettiest solution, but the most pragmatic to fix the regression right now.

Mid term, it would be good to encapsulate k-table into a k-table-items wrapper component which adds support for buttons entry as individual columns.

Ready?

• In-code documentation (wherever needed)
• Unit tests for fixed bug/feature
• Tests and CI checks all pass

For review team

• Add lab and/or sandbox examples (wherever helpful)
• Add changes & docs to release notes draft in Notion

I quite like it. It's indeed not pretty, but pretty pragmatic :)
