feat(rituals): switch icon from Lightning to ArrowClockwise

Lightning was inherited from the ai-rituals era (AI-feature vibe) and
didn't match what rituals actually express — recurring, cyclical
practice. ArrowClockwise reads as "loop / recurrence / do this
regularly", which fits both utility and ceremony flavours.

Lightning is kept for `automations` (still the right match there).
