fix(base): replace Popover with Menu for view-tab context menu

The Rename / Delete-view popover (right-click on a view tab) wasn't
closing on outside click or Escape. The container was a <Popover>
with hand-rolled <UnstyledButton> menu items — closeOnClickOutside
and closeOnEscape on Mantine Popover only fire onClose when focus is
inside the dropdown, which never happens here because the popover
opens via a context-menu (focus stays on body) and there's no
trapFocus.

Switch to Mantine <Menu>, which is purpose-built for this pattern:
closeOnClickOutside / closeOnEscape work without focus being inside,
closeOnItemClick removes the manual setMenuOpened(false) wiring on
each item, and the keyboard arrow-key navigation is free.
