Contract 6.3.0

A name beside every tag the console had been showing bare. Three envelopes gain a last-observed name so a reader need not make a second call to say who a record is about.

• battles_query: top-level name beside player_tag when the call named one subject (the page's rows carry it; an empty page still names who), and me.name beside me.player_tag on each row when it did not (a battle by id, a deck across the corpus). Null when the record has no name for the tag.
• battles_decks: top-level name beside player_tag.
• war_history: top-level name beside clan_tag.
• players_search: each match carries clan_name beside clan_tag (null when the clan is unnamed or the player is in none).

Additive.
