feat: move Remote Dev below Flash, add SSH terminal button, enlarge tab font

- Reorder NAV_ITEMS: remote moved to index 1 (below flash)
- Update stack widget order and lazy-load indices accordingly
- Add "Open Terminal" button in Remote page, enabled after SSH connect
  - Linux: tries gnome-terminal / konsole / xfce4-terminal / xterm
  - Windows: opens cmd with ssh command
- Increase tab filter button font-size from 11px to 14px (theme.py + skills/page.py)
