fix: resolve font upload "baseUrl is not defined" error (#235) (#297)

The baseUrl variable was declared inside an IIFE that skips re-execution
on HTMX reloads, so it became undefined when the fonts tab was reloaded.
Since baseUrl was just window.location.origin prepended to absolute paths
like /api/v3/fonts/upload, it was unnecessary — fetch() with a leading
slash already resolves against the current origin.

Remove baseUrl entirely and use relative URLs in all 7 fetch calls.
