refactor stuff while working on another task

[joanise]

PR Goal?

Do some code clean up and refactoring while I'm working on another project.

Spliced into a separate PR for easier reviewing.

Fixes?

• BaseModel.json() has been deprecated, use the current model_dump_json() function instead;
• typer documentation now recommends using Annotated[] for declaring arguments with a base type and additional type metadata: converted everyvoice/cli.py to use this syntax;
• enabled "no args is help" so that everyvoice and everyvoice train, e.g., are now equivalent to everyvoice -h and everyvoice train -h.
• test_utils, once it accidentally leaves a directory behind, keeps failing systematically afterwards. Give the developer an explicit warning about that and instructions on how to fix it before rerunning the tests.

Confidence?
