add DEFAULT_NEWORK in .env.example and use it in settings.ts

[stormsson]

settings.ts uses snapshot.utils.getSpaceUri without the network parameter;

When running on a network different than mainnet (like rinkeby ) there is no way to pass it here.

• added DEFAULT_NETWORK param to .env.example to configure the network id to use (example value = 1 to use mainnet to grant retrocompatibility)
• altered settings.ts to fetch & use env var (with fallback value of "1" to grant retrocompatibility )

NETWORK

snapshot-hub/src/graphql/helpers.ts

Lines 43 to 44 in fa64304

	const networkStr = network === 'testnet' ? 'demo.' : '';
	proposal.link = `https://${networkStr}snapshot.org/#/${proposal.space.id}/proposal/${proposal.id}`;

SNAPSHOT_URI:

snapshot-hub/src/events/index.ts

Line 51 in fa64304

deep_link: `${process.env.SNAPSHOT_URI}/#/${event.space}/${event.id}`

and now there's DEFAULT_NETWORK.

This is a bit confusing but NETWORK could actually be removed and replaced by SNAPSHOT_URI. It does nothing more than building the frontend URL for proposal links and/or push notifications.
