Remove bootstrap from the default app generators and new app template

[crimson-knight]

Amber is currently tightly coupled with Bootstrap 4.

Pros:

• This makes it easy to get started with some styling built in
• Less configuration out of the box

Cons:

• It's tied into every generator (new apps, scaffolds and views), making more work to use a different front-end framework
• It's using Bootstrap 4, but the latest is Bootstrap 5
• Upgrading Bootstrap 4 -> still means some of the older classes get mixed in and create more work to change the generated views

Let's remove Bootstrap entirely.

• The default home page should be built using inline CSS
• The scaffold generators can stop adding to the navigation layout during generation
• Generated views should be minimal HTML with maybe some inline CSS for bare minimum styling

This sets the path for easier customization of templates for new Amber users.

@crimson-knight Agree. We should go all the way and remove node/npm dependency as well. use HTMX and keep CSS < 100kb.

I would love to remove the node dependency entirely. Is there a shard to do that though? Seems like everything these days for styling is handled by a JS bundler

[drujensen]

If we go minimal like you are suggesting, you don't need any of that stuff. I will work on this when I get a chance.

Cool thanks Dru. I checked out htmx, looks sweet!

Including a copy of htmx for our asset pipeline to start is a good way to allow for installing Vite or some other JS/asset bundler for styling should anyone want to implement it.
