Remove text from action buttons

[Aprillion]

New design Figma in #285 has action buttons without text, while PR #330 added a 3rd button in the old design => let's remove the button text. Please double check white space (balanced distance from text and borders) and align with tags (desktop/mobile, light/dark/embed).

Current order is 👍👎✏️, but if a future redesign counts with different button order, removing text is the best opportunity to change button order without breaking someone's muscle memory => if the future order will be defined before implementing this issue, let's use the new order.
