[Bug]: `deno deploy create` broken

### Problem description

The `deno deploy create` flow has various bugs that make local, non-GitHub deployment difficult and requires switching to the website.

### Steps to reproduce

1/ If I enter `deno deploy` in a new repo, it only lets me select an existing app, not create a new one. Not sure if this is expected or not, but noting it. There is a minor TUI render buffer issue as I navigate this menu as well.

2/ I switch to instead use: `deno deploy create` and I see the error:

```
Usage: deno deploy create [root-path]
# ...
error: Missing required option "--org".
```

This is unexpected as docs and my memory say there's supposed to be an interactive create mode.

3/ I one by one add arguments until the command proceeds: (`--app, --source, --region, --org, --entrypoint`)

It then gives me a new error, until I provide: `--source local --app-directory .` which I needed to use trial-and-error as it wasn't clear from the error (shouldn't these be default?)

4/ The deploy command progresses, but fails due to no entrypoint. It seems that my `--entrypoint` argument does not propagate to the serverside configuration. I have to manually enter it in `app.deno.com`.

5/ Finally, I realize I accidentally included a file with an error in it. I delete this file and redeploy, but it seems to be cached and persisted in the app. I have to delete the app and start over.

6/ Now, the app is successfully deployed. Note that even knowing the optimal path now, it still requires navigating to the site each time due to step 4.

### Expected behavior

I'd expect the interactive `deno deploy` flow to work without errors and undocumented behavior, and without requiring navigating to the website to create new apps.

### Environment

Deno v2.7.7, macOS
