improvement(ui): drop full-content hover tooltips

- remove the chunk-content tooltip in the KB chunks table (it forced the full chunk body on every truncated row)
- remove the sub-block value tooltip on collapsed workflow blocks (whole prompts/code/JSON on hover)
- replace the native `title` on subflow and note blocks with the clip-gated OverflowSpan
- clip-gate the KB documents tags cell so it stops firing on fully visible tags
- drop the dead tooltip on the resource header root title, which can never truncate
