fix(ci): resolve biome lint issues and harden auto-fix push step

- Add biome-ignore on normalizedBody variable (used in Astro template,
  outside Biome JS scope) to prevent false unused-variable warning
- Apply biome import order: sort imports alphabetically in demo pages
- Apply biome ternary formatting in Icon.astro (cosmetic only)
- Use --force-with-lease on push to guard against concurrent pushes
  while still protecting against accidental overwrite of others' work
