documentation updates

# Description/Steps to reproduce

1) https://github.com/ChickenKyiv/recipe-api-only/blob/master/docs/FreeMenu.md
as you can see - images are broken and i think i delete them from main repository.
in previous releases i think you'll find them: https://github.com/ChickenKyiv/recipe-api-only/releases
But please move that images to this repo: https://github.com/ChickenKyiv/creative
I'm trying to make code as clean as i can.

2) here you also can figure out that i upload logos of ChickenKyiv(CK) project.
https://github.com/ChickenKyiv/recipe-api-only/tree/master/client/assets/logo
https://github.com/ChickenKyiv/recipe-api-only/tree/master/docs/logo

But some of files are duplicated and also moved to https://github.com/ChickenKyiv/creative/tree/master/logo

You need to compare that files and move non-duplicates into `creative` repo and delete them from `recipe-api` repo

3) at `creative` repo we have a file, related to our current DB schema. But we also have it in `recipe-api`.
Please remove it from rapi and replace path at readme file - so image will be picked from `creative` repo.

# Expected result

# Additional information

Start by checking docs/FreeMenu.md and the linked release assets to identify the missing images. Compare client/assets/logo and docs/logo with creative/logo, then review the database-schema file and README reference mentioned in the issue. Done means non-duplicate assets and the schema image are in creative, obsolete copies are removed from recipe-api, and links still resolve.
