Description

When your direct membership of a space is removed but you still have access through a group (or the other way round), the space now stays listed and you're not told your access was revoked; your permissions just get updated.

Related Issue

• Fixes Space disappears from the overview when the direct membership is removed but group access remains #4305

How Has This Been Tested?

• test environment: unit tests (Vitest), browser tests (Playwright) against a local OpenCloud
• test case 1: unit: space member removed SSE handler keeps the space when /me/drives still returns it, and removes it (with the message) when it doesn't, including an admin who could still fetch the drive directly
• test case 2: browser: group + direct member losing the direct membership on the Spaces overview and inside the space, group removed while direct membership remains, direct-only member removed, admin removed without group; member added and role changed still update live
