[frontend] Popover event menu support for FAB_REPLACEMENT feature flag

[ParamConstructor]

Proposed changes

These changes apply to the Events menu items in support of the popover removal as part of the FAB_REPLACEMENT feature flag.

• Remove the ... popover icon.
• Move the "Delete" from this popover into the Drawer for the item, have the button be on the bottom left of the drawer in red
  • Note - Sightings already has delete on drawer by default.
• Float the Enrich option to the top row and use the default cloud enrichment icon
