test: Access for owners and collaborators

[SilviaZeta]

Description

• adds tests on access for owners and collaborators
• switch to @gliff-ai/style icons

note: the act function from React Testing Library is used to address the warning " Warning: An update to ProjectsView inside a test was not wrapped in act(...).", which indicates that some changes happen only after the test has finished (e.g., some state being set). The warning was there for all views.
