-- Simplify the operating tree: drop the separate ADIF-value columns (we
-- now use the display name as the ADIF MY_RIG / MY_ANTENNA value — one
-- field per row, no duplication) and add per-rig TX power so the entry
-- strip can stamp TX_PWR alongside MY_RIG when the band changes.

-- SQLite can't DROP COLUMN safely on every version we support, so we
-- recreate the tables. operating_antenna_bands is left untouched — its
-- schema didn't change — but the FK on operating_antennas needs to be
-- rewired since the table is recreated.
