Sort Checkpoints and LoRAs alphabetically

[kyeno]

This simple PR fixes the right menu's "Model" tab to ensure the Checkpoints and Loras are always sorted alphabetically.
Both at startup and after clicking "Refresh All Files" button.

@lllyasviel knock knock?

as of https://github.com/lllyasviel/Fooocus/blob/main/modules/util.py#L177 models + checkpoints should already be sorted correctly. Can you please double-check if the existing implementation is not working for you and provide a screenshot of your model list + your Gradio model output? Thanks!

@mashb1t Hey! Nope, they're not sorted alphabetically unless that mini PR of mine is implemented.
Here are the screenshots of the main branch:

As you can see I have a tendency to rename the LoRAs for some extra management with Fooocus (thinking about making a bigger UI change PR when I get some time), but that's not really an issue.

If this may help you debugging anyhow, my PC is running:

• Debian Linux 10.X with self-compiled kernel 6.5.8
• Python 3.11 with pip 23.3.2
• Official Nvidia driver 535.113.01 with OpenCL 3.0 CUDA 12.2.146
• Brave Browser 1.61.109 based on Chromium 120.0.6099.144

And HW details (which are likely irrelevant, but who knows at the end):
AMD Ryzen9 5950X 16c/32t @ 5.1GHz, 32GB G.Skill DDR4 3600MHz, EVGA RTX 3090 24GB GDDR6X, 1TB Samsung 980Pro NVMe PCI-Express 4.0 SSD (whole SD engine, models, loras, etc; makes a difference).

Btw also; I'm not a Python expert (yet ;)), but that line you linked could be the culprit. The lambda depending on os.sep may be returning wrong on Linux.
I could test it out a bit in a free while, though I do not have any Windows or Mac machines at the moment for comparison.

[mashb1t]

@kyeno the issue had to do with the condition of the lambda. os.sep returns correctly, but the sorting of the else condition just appends to the end and beginning, which is wrong. I've now implemented sorting for files when walking as well as topdown=False to display subfolders first.

I couldn't change files in your PR, so there now is a separate PR: #1784
Closing this PR & thank you very much for your ideas and your effort, much appreciated 👍
