fix(tui): pager supports scrolling (up/down/page/top/bottom)

The pager overlay backing /history, /toolsets, /help and any paged slash
output only advanced with Enter/Space and closed at the end. Could not
scroll back, scroll line-by-line, or jump to endpoints.

Adds Up/Down (↑↓, j/k), PgUp (b), g/G for top/bottom, keeps existing
Enter/Space/PgDn forward-and-auto-close, and clamps offset so
over-scrolling past the last page is a no-op.
