feat: Add optional APP_LOGO branding to the scaffold

[ek9r]

Add support for an optional APP_LOGO environment variable and use the official Tempest logo as the example configuration.

When configured, the logo is rendered above the Tempest heading on the home page.

The official logo is provided as an example in .env.example:

APP_LOGO="/img/tempest-logo.png"

The included tempest-logo.png is sourced from the official Tempest branding repository.

If APP_LOGO is not set in the application's environment, no logo is rendered.

The custom logo assets in public/img/custom/ are community-created demonstrations and a small fan tribute from the German-speaking PHP user group community, including the PHP elephant as a nod to the wider PHP ecosystem. They are kept separately from the official branding and may also serve as examples for future custom/community branding.

And, well… a little fresh breeze never hurt the PHP elephant. 🐘💨

I'm confused, these aren't Tempest's official logo? https://github.com/tempestphp/.github/tree/main/logo_current

You're absolutely right @brendt
that wasn't your official Tempest logo.

It was created as a demonstration/community asset and as a small fan tribute. We like it enough that we're about to have T-Shirts printed with it as our little Tempest fanboy outfit. 😄

I've updated the PR description.

You're absolutely right

Ok so I've got to ask how much AI is involved in this conversation 😅

To be clear: I think part of this PR makes sense, but I don't understand why another logo should be shipped with the default app?
