Issue location: /organisation/<org_id>/permissions?type=roles

The problem is observed when in dark mode.

When associating tags to permissions in the "Edit Role and Permisions" dialog, the label of the tag is barely readable because of the low amount of contrast between the font color and the background color.

See demonstration:

Disclosure: the label "ABCD" in the screenshot above was artificially added in order to redact real information, hence looking oddly sharp compared to the image resolution. Reality looks worse.
