allow to select endpoints to be rendered non-interactive

Currently user needs to go through `questionary` UI to select the endpoints. we should allow this command to run non interactive.
those are just ideas:
- add a flag that will generate all the endpoints
- add a filter by tags
- add a filter that looks like file glob where several api paths could be specified

Start by tracing the command's endpoint-selection flow and its use of the `questionary` UI. Clarify which non-interactive selection modes are required—render all endpoints, filter by tags, or match API paths with file-like globs—and define completion criteria for each before locating the relevant command code and tests.
