1. A language change rebuilt the column defs, which sets the anti-clobber
guard, but the effect that clears it listened to only two of the rebuild's
causes. Guard stuck on → every column change was silently discarded for the
rest of the session. Now keyed on the rebuilt defs themselves, so any future
cause is covered.
2. The cluster grid had no guard at all: the same rebuild wrote its defaults
over the saved layout, in the cache AND the database. Unrecoverable.
3. Worked-before and cluster read their state before the active profile was
known, so they looked up the unscoped cache key (always a miss) and then
saved under the scoped one. They now wait for the scope and remount on a
profile switch, like the main log.
4. GetUIPref returns an ERROR, not "", while the settings store is not yet
scoped — deliberately distinct from "unset". The frontend read it as "no
preference", rendered defaults, and the first column event overwrote the
good copy. It now retries instead of giving up.
5. The QSL manager had no storageKey, so it shared the main log's layout and
each rewrote the other.
Also: the DB write is debounced (a resize drag fired dozens of writes) with a
flush on close, and a rejected write is retried rather than dropped.
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.
