2026/10/20 Fixed 5 issues including the zoom level menu going off-screen

The following 5 issues have been fixed.

• The zoom level menu at the bottom of the screen could extend beyond the screen and become unselectable, but it now appears within the screen.
• When navigating to adjacent nodes while a node's details were open in flow view, the target node could remain outside the visible area, but it now moves to a visible position.
• When opening a process with many labels on a narrow screen, the Process Name could become invisible, but it is now displayed correctly.
• When deleting shared users or changing their permissions failed, "Save failed." was displayed, but the message now corresponds appropriately to the operation performed.
• When the deletion of shared users and permission changes occurred simultaneously, there could be no remaining editor for the process, but now at least one editor will always remain.
