Store an optional company name on Ticker (migration 014) and backfill it from Alpaca's asset list in a single Trading-API call for the whole universe — no per-ticker fetch. Runs automatically at the end of universe bootstrap and via a manual "Backfill Names" button (admin) / POST /admin/tickers/backfill-names. The name ships on /tickers; a shared symbol→name map (useTickerNames) lets any view show it without its own request. Displayed subtly next to the symbol — in the global search, the ticker header, and as a small muted line under the symbol in Top Setups and Open Trades (no extra column, truncated so it never widens the table).
