Explore fixes from a signed-in walk

A signed-in walk of the console found, and this fixes: battle pages in Explore that failed to open, a player's deck list too large to load, war weeks that showed no rank or fame, a clan's members all reading "never" for their last battle, and the activity chart's newest weeks hidden on a phone. Explore accepts a war week typed as 136-2, a connection's last call is its last real call, the tracking pages describe the polling schedule as it runs, and a badge question about a player Elixir has never read says the answer is unknown.
