ids theme: align list markers flush with the slide title

Native ::marker glyphs are anchored by the browser with engine- and
font-dependent offsets, so the bullet column never lined up exactly with
the heading text. Draw the markers as CSS boxes in absolutely positioned
li::before rules instead: dot/square/ring per nesting level, vertically
centered on the first line, with the first-level marker's left edge
deterministically flush with the title in every browser and at every
window size. Nested offsets scale with the 0.8em per-level font-size
cascade. Ordered lists use the CSS list-item counter (honours start/
value), right-aligned into the indent; pandoc task lists keep their
checkboxes.
