fix: alignment of votes and icons within notes of the stack view

[brandstetterm]

Description

The original problem has been that the icons of the various buttons within a note (e.g. add vote, unstack note, delete note) in the stack view were not aligned. However, further problems were subsequently found. For example, I noticed that the buttons have different sizes and that the tooltips of the delete and unstack buttons also overflow outside the screen on narrower screens. For this reason, I've tried to come up with a better alternative for the buttons within the notes.

Fixes #3843

Changelog

• Use the same height and width for all buttons within the notes (e.g. add vote button, delete button, unstack button)
• Replace the tooltip buttons with normal buttons in combination with our new tooltip component

Checklist

• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• The light- and dark-theme are both supported and tested
• The design was implemented and is responsive for all devices and screen sizes
• The application was tested in the most commonly used browsers (e.g. Chrome, Firefox, Safari)
