Pages section table: add field types for columns

[distantnative]

This PR …

Enhancement

• Page and files section with table layout will now try to infer the column type from the blueprint of the first model when no type has been provided explicitly

Breaking changes

I think none as columnsWithTypes is a new function that our pages/files section uses - but any plugin extending those sections can still use columns like before.

For review team

• Add changes to release notes draft in Notion

What happens when one of the pages has a different blueprint with different field types?

@bastianallgeier Would clash. But no idea how to resolve that.

I wonder if the table layout should actually be limited to pages sections that only define a single template. That would make a lot of sense, not only if we implement this.
