fix(FN-2400): harden dashboard TUI log viewport budgeting

- Rework logs viewport calculation to budget by rendered rows and keep content above footer hints
- Add zero-row safety handling for short terminals with a dedicated expansion hint instead of overlapping output
- Cap wrapped log rendering by remaining row budget so long messages cannot overflow into footer space
- Add regression tests for footer-safe list windowing and wrapped-line truncation, plus a patch changeset for @runfusion/fusion
