HTTP API: update /xb-render-component/{component_id} to use Component config entity's default values

This blocks @bnjmnm over at 📌 Add component instance edit form to contextual panel RTBC .

✨ Allow specifying default props values when opting an SDC in for XB Fixed is in.

⚠️ Note that this won't fix the problem demonstrated in the issue summary's GIF for the component, because for that 📌 [PP-1] Default props values should support files/images Postponed must first happen on the config management side.

With this in place:

Oops, sorry for overwriting your merging of upstream commits, @bnjmnm, that was unintentional 😅

Working to get this issue's status/relevance updated, but blocked on @lauriii's confirmation at #3463999-7: [PP-1] Auto-generate Component config entities for all discovered SDCs that meet XB's minimum criteria → .

This is no longer a blocker though.

📌 Auto-create/update Component config entities for all discovered SDCs that meet XB's minimum criteria Fixed is now in. Thanks to that issue, the following if-test is obsolete — that is now a requirement for an SDC to become available in XB:

      // @todo Revisit in https://www.drupal.org/project/experience_builder/issues/3455942.
      if ((isset($prop_info['examples']) && isset($prop_info['examples'][0])) || in_array($prop_name, $metadata->schema['required'] ?? [])) {

I'll push this forward tomorrow. It's been lingering too long, and I'd like @f.mazeikis to remain focused on 📌 [PP-1] Add support for Blocks as Components Active .

Now properly ready for review! 😊

My title update was lost 😬

Re-ran pipeline and it's now passing. Code looks good too - certainly an improvement, even if we still need to come back to this once we have solutions for datetime and image (and entity references in general) props handling.

Automatically closed - issue fixed for 2 weeks with no activity.
