fix: make paginated tables fit terminal dimensions

[aidandaly24]

Summary

• render the DataTable filter prompt in the existing divider row so filtering does not change table height
• increase the terminal-derived page size by one so full paginated tables reach the footer
• make Runtime Version and Harness Version tables fill the available terminal width
• keep footer hints on one row by switching to compact key-only hints when labels do not fit
• cover all production table width configurations and the paginated 60x24 layout with regressions

Testing

• bun test src (587 pass, 0 fail)
• focused DataTable and pagination tests (27 pass, 0 fail)
• source-scoped TypeScript check excluding ignored generated dist assets
• bun run lint:check
• bun run format:check
• bun run build
• live Runtime Version and Harness Version validation at 120x32
• live paginated Runtime List validation at 60x24
