chore: align biome schema version with CLI latest

Bumps biome.json $schema from 2.4.4 to 2.4.14 so the repo schema
matches the version the 'Auto Format' workflow installs via
@biomejs/biome@latest. Also applies the one auto-fix the newer
version produces (export ordering in electron/electron.d.ts).

Fixes the spurious 'This PR has formatting issues' CI failure that
was blocking fork PRs unrelated to formatting.
