feat: materialize award references into the QSO row (award_refs column)

Award refs are now computed once and stored on the QSO as a JSON column
(award_refs, e.g. {"DDFM":"74","WAJA":"12"}) instead of recomputing the whole
award engine on every grid page load. Written on log/edit/UDP-import and
bulk-recomputed when an award definition or reference list changes; a one-time
per-logbook backfill materializes pre-existing QSOs. The grid reads the column
directly like any other field, so it's fast and available everywhere (including
the shared MySQL logbook).

Also fix per-profile grid column layout: the DB copy was already per-profile,
but the localStorage cache used one global namespace and shadowed it, so a
profile switch kept the previous profile's columns/widths. gridPrefs now scopes
the cache by active profile id and the grids remount on profile:changed.
