[Web] Respect permissions of the authenticated user

[exalate-issue-sync]

Description

User Stories

• As a user I only want to see the parts of the UI that my permissions allow me to use so that I don't get confused by unusable features.

Value

Acceptance Criteria

• fetch permissions via ocis settings API and store them in memory in the permission manager
• respect permissions as defined by the role of the authenticated user. Existing permissions:
  • set-space-quota
  • list-all-spaces
  • create-space
  • account-management
  • group-management
• double check that there are no checks on the user role in the code anymore: user?.role?.name (or variants without optional chaining)
