Added uniswap trade widget

Closes: #9887

Description of Changes

Added uniswap trade widget to trade tokens post launchpad phase. Trading will not work on tokens launched via common as they are launched on base sepolia, while the modal will use base network, it will only work for the tokens that are already on base. In our implementation, we added USDT, USDC, WETH as token swap options.

Test Plan

Note: Custom tokens launched via common will not be tradeable via the uniswap modal.

Pre-req

1. Apply this change to enforce uniswap widget modal for every token trade (this is only for testing, and this will automatically be set when token reaches market-cap goal/post-launchpad-phase on common) - this basically tells the modal to show swap mode instead of buy/sell via common.

Steps

1. Create a token community.
2. Click on the swap button for that token (this "Swap" button will be displayed inside community and on the communities explore page for that token, test both of these flows)
3. Verify you see the chain switch modal in your wallet (if your wallet is not on base network)
4. Verify you are able to see the available base eth amount in your active address, in the modal.
5. Verify you are able to switch tokens. (Plz don't select the community token, as it won't be testable, see above for more info)
6. Verify you are able to complete a trade successfully. IMPORTANT: the test is on base mainnet, so it will require real tokens.
7. Verify the modal remains open after the trade (to show basescan link and other transaction details). The whole flow should look like this
