RM-3898: authtoken check

* use '/key-shares' OAS 1.0.1-draft
* requires cdoc2-client:SID-1.6.1-SNAPSHOT 
* Check authToken by using rules defined in https://gitlab.ext.cyber.ee/cdoc2/cdoc2-documentation/-/blob/RM-2776-authentication-protocol/cdoc2-system-docs/docs/03_system_architecture/ch05_ID_authentication_protocol.md?ref_type=heads#verifying-sd-jwt-verifying-authentication-ticket
* Clean-up unneeded dependencies and remove shared-crypto submodule that contained single class and name clashed with shared-crypto submodule from capsule-server
* Rename submobules from `cdoc2-server-db` and `cdoc2-server-openapi` to `cdoc2-css-db` and `cdoc2-css-openapi` so that these don't clash with existing modules from cdoc2-capsule-server submodules.
