Account view's Balance link redirects to /rewards instead of /txs

[tjb-altf4]

Currently both Account view's Balance and Rewards link redirect to /rewards.

Instead, Balance should redirect to /txs, as per below below.

link Text	link construction
Rewards	explorer.spacemesh.io/accounts/<account_id>/rewards
Balance	explorer.spacemesh.io/accounts/<account_id>/txs

Actually this is partly incorrect, because of course transactions link will show you transactions slaps head
However, as Transactions only shows a count, and not an overall balance like Balance does/should, it is still more suitable to link to /txs rather than /rewards

This issue may be redundant if #203 is implemented

#203 was implemented and "Balance" line was removed. Closing.
