[pbs-devel] [PATCH widget-toolkit v1 1/3] fix #4001: FileBrowser: add menu to button and selected entry label

[Stefan Sterz <s.sterz@proxmox.com>]

this commit adds a label showing the currently selected entry in the
file browser and merges the "Download .tar.zst" and "Download .zip"
button into one menu button.

note: i am not really a fan of decoding the filepath via `atob()` 
here, but that is how the data is sent from PBS. if you have
suggestions on how to improve this, feedback is appreciated.
