chore: tree shake chain and account modals

[magiziz]

Changes

Applied tree shaking for chain and account modals to prevent them from bundling when unused.

Screen recordings / screenshots

Here you can see that account and chain modals are bundled separately if they're being used.

What to test

• Whenever you don't use useAccountModal hook you shouldn't see account modal being bundled in network tab.
• Whenever you don't use useChainModal hook you shouldn't see chain modal being bundled in network tab.
