When directly opening the source/extension browse page as the initial page, the metadata server settings weren't loaded yet, and thus, the default values were being used.
Thus, when opening the dialog the first time, it was showing the default selected languages.
Switch to "lingui" for better DX.
Tried to persist existing languages as much as possible.
Removed "vite-plugin-node-polyfills" because it's incompatible with "lingui"
