[Bug]: Cannot use spaces in markdown page names

[archiewood]

Describe the bug

Upgraded from 39.1.13 of evidence in my local development environment and recently tried to upgrade to version 40.0.1.

Markdown pages that contain special characters now break eg white space.md

Steps to Reproduce

Add a page with a space eg page two.md and try to navigate to it from the sidebar

https://github.com/user-attachments/assets/b7b4e231-6678-48a1-8d56-efa9cbeddeef

it's detecting the pre encoded space character %20 and then encoding it again, replacing the %-> %25 so overall you get page two.md -> page%20two -> page%2520two

You are welcome to take a look at it. I'd suggest looking in Sidebar.svelte to begin with.
