-- QSL_SENT_VIA / QSL_RCVD_VIA — the ADIF fields that say HOW a card travelled.
--
-- Until now OpsLog had one column, qsl_via, and used it for two unrelated
-- things: the QSL manager (what ADIF's QSL_VIA holds) and the routing method.
-- Imports made it worse — QSL_SENT_VIA was folded into qsl_via when qsl_via was
-- empty, so a Log4OM log arrived with "E" sitting where the manager belongs —
-- and QSL_RCVD_VIA was dropped outright, listed as a promoted field with no
-- column behind it, so it was not even kept among the extras.
--
-- These two columns hold the ADIF enumeration: B (bureau), D (direct),
-- E (electronic). M (manager) is accepted on import only, per the standard.
--
-- Adding the columns is all that happens here. Existing qsl_via values are NOT
-- touched: separating a manager from a routing word rewrites what an operator
-- can see in their own log, so it is offered once, with a count, and only runs
-- when they say yes.
