Replaces the old suggestion of setting JS head 'window.uploadLimit'
variable. This new env option will be used by back-end validation and
front-end libs/logic too.
Limits already likely exist within prod environments at a PHP and
webserver level but this allows an app-level limit and centralises the
option on the BookStack side into the .env
Closes#3033
- Files within the storage/ path could be accessed via path traversal
references in content, accessed upon HTML export.
- This addresses this via two layers:
- Scoped local flysystem filesystems down to the specific image &
file folders since flysystem has built-in checking against the
escaping of the root folder.
- Added path normalization before enforcement of uploads/{images,file}
prefix to prevent traversal at a path level.

A query string will cause attachments to be provided inline
with an appropriate mime type.
Remaining actions:
- Tests
- Front-end functionality
- Config option?
This filters out potentially malicious javascript: or data: uri's coming
through to be attached to attachments.
Added tests to cover.
