UX Consistency Fixes for UX Styling inconsistency

This is the first part of the UX Consistency Fixes for Inventory, covering UX Styling inconsistency.

The UX team has reviewed Inventory and identified several minor changes that are needed for the Inventory app to be consistent with the rest of FOLIO:

UX Styling Inconsistencies:

1. Pressing the “X” button, in “Editing record & Add new holdings” page, has to redirect you to the previous page with no warning modal.
2. “Editing record & "Add new holdings” page has the wrong design on the delete/trash icon, it has the wrong color and size: Find design of the icon (light grey) here - https://ux.folio.org/docs/guidelines/ux-patterns/edit-record/#media-8547
3. “Edit record detail” input fields should follow the new rule of the accordion core section. The title of the accordion core should have big input fields etc..
4. When you focus an item a bullet dot appears to the left side, this shouldn’t be there.
