Integrate thumbnail: Don't change folder thumbnail

[iLLiCiTiT]

Changelog Description

Do not set folder thumbnail during publishing. And unset the thumbnail on existing folders.

Additional info

Update of folder thumbnail can trigger recalculation of calculated attributes. Also setting the thumbnail id is not necessary and can be skipped.

To "auto-fix" folders that already do use the thumbnail from version was added a cleanup endpoint that does remove the thumbnail before version thumbnails are pushed to server.

Testing notes:

1. Thumbnail integration still works and folders do have thumbnails.

Overall looks good to me - just needs the query code check and there's a minor variable name typo. @LiborBatek can you test this with regular artist user and admin user and see if it holds up fine? Run it across two different folders for both runs and they must both have had publishes with thumbnails from before this PR/branch.

Im experiencing some warning info msg when using captured thumbnail...not sure if related or irrelevant, so pls tell me @iLLiCiTiT

When the version does have any thumbnail it correctly get propagated from version to the folder or rather product which is good.

Now what Im not so sure is whenever producing a product version which doesnt have any thumbnail it also propagates to the product and removes any existing thumbnail too...resulting into empty thumbnail on the product. Again Im not sure if thats correct or not even tho it sounds logical to me...

So my conclusion been, if any thumb present on the version it gets correctly propagated, and if not it also propagates "nothing" and thumbnail not present.

On the Folder / Tasks all thumbnails stays intact if any existing...which is correct.

[LiborBatek]

I have tested using 2 distinct users (admin vs regular artist) and all seems working fine...

There are few questions from me above but I guess they are not relevant to this PR but rather how Ayon works with thumbnails/reviewables...feel free to answer those or even take those into account if connected to this PR.

Thumbnails simply stay intact when already present on a Folder and Task level and each version propagates accordingly to the product itself (whether its thumbnail or empty aka nothing).

Seems ok to me.

I think the above warning you mentioned actually indicates an issue - so let's make sure to double check this @iLLiCiTiT

Pull request overview

This PR adjusts thumbnail integration to avoid explicitly setting folder thumbnails during publishing (to prevent recalculation of calculated attributes), and adds a server-side cleanup endpoint to unset existing folder thumbnails that share the same thumbnail as a version.

Changes:

• Update thumbnail publish integration to only set thumbnails on versions (not folders) and trigger a cleanup call for affected folders.
• Add a core server addon POST endpoint to clear folder thumbnail_id values when they match a version thumbnail.
• Minor logging/message adjustments around thumbnail detection and upload timing.
