refactor(automations): rename "Delayed execution" to "Wait" in the builder

Adopt the simpler Wait concept (as Intercom et al. use): the toggle is labelled
"Wait", the duration reads "Wait for [4] [Hours]", and the block moves to just
before Actions (it applies to the whole rule; if we add ordered steps later it can
become a proper Wait action). The "Runs after 4h" list badge is unchanged, and the
engineering layer (execution_delay column, delayed_automations flag) keeps its name.
