enh: Polish inline editing fields

[enjeck]

Fixes some of #2054

• Richtext: There should be no jump in the whole table when a user clicks in and out an inline editable field
• Textline: Fields should activate edit mode with just one click
• Richtext: We should not show drag handles or + icons in text fields that are not currently being edited
• Stars: The stars shouldn't change in style and size, they should stay of --color-main-text and with the same distance
• Switch: Don't show scrollbars
• When editing rich text inline, some things are clipped (like when creating a heading the # icon). It also has a big black border it isn't supposed to have.
