feat(single-api): single api functionality

[matbmoser]

[!CAUTION]

FIRST MERGE PARENT PR: #306 !

Why we create this PR?

To create a Single API Post method that allows to retrieve the passports data by abstracting of all the API's calls needed to do so, by authenticate with an API Key and fill the requested data in the body.

What we want to achieve with this PR?

We want to be able to retrieve the passport with only one API call.

What is new?

Added

• SingleApiRequest class for the requested data for the single API.
• SingleApiConfig class to had configurations related to the single API.

Updated

• Updated ApiController with the singleApi POST method.
• Updated ContractController by creating call methods (create, search, agree and status) without the authentication step to call in the Single API.
• Updated AuthenticationService by adding the isSingleApiAuthenticated method to authenticate the single API key.
• Updated application.yaml with the single api configurations.
• Updated deployment-backend.yaml with the oauth.apiKey.
• Updated values-int/beta/dev.yaml files with the oauth.apiKey.
• Updated spring boot to version v3.2.5 from v3.2.4
