refactor: remove unnecessary updating of token balances on quickswap

[0xAlunara]

The following PR reasons about the existing store + fetching infrastructure. In the future, we will replace it with hooks + queries, but for now:

1. The dex global slice calls await state.pools.fetchPools(config, curveApi, poolIds, failedFetching24hOldVprice) during hydration

2. fetchPools fetches all pool user balances with the following snippet:

   const partialTokens = await tokens.setTokensMapper(curve, partialPoolDatas)
   
   if (curve.signerAddress) {
     void userBalances.fetchUserBalancesByTokens(config, curve, partialTokens)
   }

   Therefore, during hydration all tokens balances are being fetched already.

3. In addition, inside the useAutoRefresh of the dex layout, we have:

   usePageVisibleInterval(() => {
     if (curveApi) {
       void fetchPoolsVolumeTvl(curveApi)
   
       if (curveApi.signerAddress) {
         void fetchAllStoredBalances(config, curveApi)
       }
     }
   }, REFRESH_INTERVAL['5m'])

   Therefore, all user balances already get periodically updated and hence we can remove:

   useEffect(() => {
     void updateTokenList(config, isReady ? curve : null, tokensMapper)
     // eslint-disable-next-line react-hooks/exhaustive-deps
   }, [config, isReady, tokensMapperStr, curve?.signerAddress])

   from the quick swap page, which gets triggered each time you switch tabs in the browser.

   In addition, user balances are also being fetched already when updating the quick swap form by setFormValues with:

   if (curve.signerAddress)
     await sliceState.fetchUserBalances(config, curve, searchedParams.fromAddress, searchedParams.toAddress)

   Which means the form will use the latest balances anyway
