feat(backend): dispatch thumbnail generation from DocumentService upload paths

Browse Source 
All four upload code paths (storeDocument, createDocument, updateDocument,
attachFile) now call thumbnailAsyncRunner.dispatchAfterCommit(id) after
the document save. createDocument and updateDocument only dispatch when a
file was actually provided/replaced.

The dispatch is afterCommit-safe: if the surrounding @Transactional
method rolls back, no thumbnail is generated for a document that never
reached the DB.
