faster loading for algos, the trade log, and sign-in

algo pages, connected broker accounts and the trade log now load faster on edgeful. broker balances load side by side instead of one at a time, and your account and strategy controls stay usable while a slow broker is still responding.

the trade log remembers days you've already opened, so switching back to a recent trade day shows your trades right away instead of loading them again.

sign-in, sign-up and checkout are smoother too. moving from the homepage to sign-in and on into the app no longer reloads the page partway through, and checkout appears without waiting on background requests. the change is most noticeable on mobile.
