Emil Lundberg 1f7d236742 gui: Specialize a special-purpose checkbox style (#9236) ...

### Purpose

Discovered while working on the WebAuthn credentials table in #9175:
there's a style on `td input[type="checkbox"]` that modifies margins for
all checkboxes in `<table>`s. It looks like this style is specially
tailored to the particular table that added it (PR #8734), so it should
have a correspondingly special-purpose class to not accidentally apply
it to other tables.

As best as I could tell there are only 2 instances of `<input
type="checkbox">` in `<td>`s, shown in the screenshots below.

### Testing

- Open "Actions > Logging > Debugging Facilities" and observe the
vertical spacing of the checkboxes.
- Open "Edit Folder > Advanced", check "Sync Extended Attributes" or
"Send Extended Attributes", click "Add filter entry" and observe the
vertical spacing of the checkbox that appears.
