Allowing other file type uploads for client documents

[RalphGL]

What version of Invoice Ninja are you running? ie v4.5 / v5
v11.03.2024.1

What environment are you running?
YunoHost

I request the possibility to configure allowed document upload file types like svg, mp4, mp3 or asc in the backend without the need patching the source code.

I've added a .env variable to handle this, in your .env simply add

ADDITIONAL_UPLOAD_EXTENSIONS="mp3,mp4,mkv"

@turbo124 can you please add this value to the account transformer so the frontend knows which extensions are allowed.
