feat: DangerButton and ConfirmButton components

[kieckhafer]

Impact: minor
Type: feature

Issue

Added three new Button / Chip components that wrap the MUI button, but give us more control of styling. Also added a fontWeightBold option in our MUI theme.

1. DangerButton, which just provides a red / danger style on top of the existing MUI button, as the provided MUI button does not come with a red / danger style.

2. DangerChip, which just provides a red / danger style on top of the existing MUI Chip, as the provided MUI Chip does not come with a red / danger style.

3. ConfirmButton, which provides a button that when clicked, opens a confirmation modal.

Testing

1. Add the buttons in places. See that they work.
