Avoid redundant terminal size queries during history insertion (#39100)

## What changed

- Pass the screen size already available to TUI draw and history-tail paths into history insertion.
- Use the terminal's cached screen size for direct history insertion calls instead of querying the backend again.
- Extend the terminal size-query regression test to cover history insertion.
