Fix overwriting of Query::$entries

[distantnative]

This PR …

For most queries, we pass along a few objects (kirby, site as well as file, page etc.). However, in doing so, we would overwrite the default entry helpers, such as page() or file().

This PR fixes it by:

• still given the data precedence that was passed along
• but falling back to the entry helpers if
  • no matching data was passed along
  • the matching data doesn't fit to the query (e.g. it's an object, but query tries to call it with arguments)

It also backports a fix from v4 regarding integer/float arguments. This commit could be skipped in the review.

Fixes

• Kirby queries can handle integers and floats as arguments currently now
• Fixed using Query helpers, such as page() alongside provided objects with the same name
  Query: default $entries not available when overwritten by provided $data #5276
