fix(x): resolve baileys build approval placeholder blocking package build

The mobile-channels feature added baileys, whose install-time scripts
require build approval. A placeholder value ("set this to true or
false") was left in the allowBuilds block of pnpm-workspace.yaml. pnpm
11 treats an unresolved build decision as a hard error, causing
pnpm install to exit non-zero and abort Electron Forge's generateAssets
hook during npm run package.

Set baileys: true to match the onlyBuiltDependencies entry.
