feat(components): add CustomAmountEditor, bump to 0.2.0

Extract the shared presets-plus-custom editor card — tonal surface with the
connected shape, an optional single-choice unit toggle, and an amount field
with a live preview + confirm — used by the reminder, agenda-range and snooze
pickers into one reusable, presentational component.
