Lifts the three-chip-plus-"+N" tag row out of ThumbnailRow into a standalone TagChipList component so the chip cap + overflow policy lives in one place and can be reused on other surfaces (document detail header is a candidate). ThumbnailRow drops from 110 to ~90 lines and no longer owns tag-slicing logic — it just asks for the list with max=3. Behavior is byte-identical: same data-testid, same max cap, same "+N" overflow indicator. All ThumbnailRow row-level tag tests continue to pass against the new composition.
