Fix Jira Cloud compatibility for search API and user identifiers

Jira Cloud has removed the /rest/api/2/search endpoint (HTTP 410).
The atlassian-python-api library already supports the replacement
/rest/api/3/search/jql endpoint when cloud=True is set.

Additionally, Jira Cloud uses "accountId" instead of "key" for user
identification. Update current_user_key and changelog field author
extraction to use the correct identifier based on the cloud setting.

To activate, set "jira_cloud: true" in the config file.
