Mainnet transaction and account links opened app-mainnet.fuel.network, which no longer shows transactions. They now open app.fuel.network.

• The mainnet network uses https://app.fuel.network/ as its explorer.
• Networks already saved in the browser with the old explorer are mapped to the new one, so existing users get the fix without clearing storage.
• Trailing slashes are removed from the explorer base, so links no longer contain //tx/.
