Rsdk-13773: viam generate app command

[allisonschiang]

This PR adds app generation to the existing viam module generate command. The implementation is straightforward: a new huh form collects app-specific inputs(I split the form into module only forms, app only forms, then shared forms that run if you generate both), then templates (mostly adapted from the https://github.com/viamrobotics/sanding-webapp repo) are rendered into a project directory. I also added tests so if anything gets changed that breaks the webapp module, the tests should fail.

Tested:

• huh form generates module for app, module, and app+module
• generated project for app builds (make setup and make succeed)
• When pointing machine to a local module, the localhost page is served the credentials to connect
• uploading a webapp module to registry creates a viam-hosted app
• single vs multi machine selection (it just fills out the meta.json field)
• app+module generation support
• local server works via cloud signaling, over network, and with no internet (need viam-server 8081 config)
• add auth.ts file and document in readme

To do:

• improve readme
• test!!!

Future Additions (maybe after this eng cycle?)

1. Local server for Python/C++ modules
2. Bubbletea dynamic forms (replace huh static forms)
3. webapp viamapplication link on machine page (its currently only on the module in registry)

`What doesn't work:

local server - could not access the :8888 from my phone on the same address`

I may be misunderstanding but this seems normal and expected? if it's a localhost address then it stands to reason that it wouldn't be accessible from a separate device.

I assumed local server meant :8888 like 10.2.3.111:8888 and then if you enable it then anything on the same network your machine is running on (with the module) should be able to access the site
