feat(settings): custom snooze duration, extract editor card to floret-kit

The Snooze-duration setting gains a Custom… option: a new single-select
SnoozeDurationPicker keeps the minute presets and adds a Custom row that
expands an amount field with a Minutes/Hours toggle, so any delay is settable
(not just the fixed presets). Closes the settings half of the snooze request.

The three presets-plus-custom editors (reminder default, agenda range, snooze)
now delegate to floret-kit's new CustomAmountEditor instead of each duplicating
the tonal editor card — the app keeps its domain math, strings and labels.

Re-pin the floret-kit submodule to the branch commit carrying CustomAmountEditor.
