* UI: checkboxes draw a rounded-square box, not a radio-button circle
The theme's 6 px widget radius made egui's 14 px checkbox box a circle,
so View > Page display's Continuous scrolling and Show cover page looked
like two more layout radio buttons. On the light theme an unticked box
had no outline and the panel's fill, so it couldn't be seen.
Every checkbox (81 call sites) now goes through widgets::checkbox /
checkbox_without_text, which draws the box with a 3 px radius and a 1 px
border outline, keeping an outline the caller already set (dialogs).
clippy.toml disallows egui::Ui::checkbox and egui::Checkbox::{new,
without_text} so new checkboxes use the helper too.

* UI: radio buttons are outlined and filled, so they show on the light theme
On the light theme the field colour is the panels' white and widgets
have no outline, so an unselected radio button (and an unticked
checkbox) was invisible outside dialogs: View > Page display showed only
the selected dot.
Every radio button (79 call sites) now goes through widgets::radio /
radio_value, sharing the checkbox helper's styling: a 1 px border
outline, text_muted on hover, and on the light theme the plain fill
(hover) as dialogs already had, keeping what the caller set. The dark
theme keeps its fills. clippy.toml also disallows egui::Ui::radio,
egui::Ui::radio_value and egui::RadioButton::new.
