reminders: adopt floret-kit multi-value override model

Bumps the floret-kit submodule to the multi-value core-reminders API
(ReminderOverride.Minutes now a List<Int>) and adapts the per-list override
plumbing + pickers to it. Agendula stays single-reminder: overrides are
one-element (or empty) lists, reminderLeadFor takes firstOrNull, and the
single-select picker wraps/unwraps listOf. On-disk format is unchanged (single
values round-trip byte-identically). Verified: :app:compileDebugKotlin.
