Add reuse compliance - Part 1

[AndyScherzinger]

As a first step convert a larger chunk of files to ship SPDX header where our converter won't be of any help...

one question maybe @elzody can help me with that. Any particular reason to replicate the server repo's image assets in https://github.com/nextcloud/tables/tree/main/cypress/styleguide/assets/img ? Just asking because I will have to replicate its license infos then.

@AndyScherzinger That was needed in order to support Cypress component tests for the interactive table widget, since the component tests don't run in a full-fledged e2e set up -- they just run by themselves, meaning we needed to import the styles, etc.

I can see now with the headers how it is problematic and creates a lot of work... not really sure initially if there's a better way to do it, since an e2e test would create a reliance on accessing the widget from another app in the tests. I can look into if there's a simpler way to do it so you don't have to re-do all of those, if possible

@elzody all good, no worries. Adding the license infos for spdx/reuse isn't an issue or a lot of effort since that info is already available from/in the server repo. So don't worry. Fine to keep the files as they are at the moment 👍
