Google replaced First Input Delay (FID) with Interaction to Next Paint
(INP) as a Core Web Vital in March 2024. This renames the DB column
from first_input_delay_ms to interaction_to_next_paint_ms, updates the
PageSpeed client to prefer the INP audit key, and fixes all references
across routes, services, scripts, and report generators. Updated INP
thresholds: good ≤200ms, needs improvement ≤500ms.
