Summary

• Fixes getGridsToBeSent() in dataproxy_sqlite.cpp which incorrectly filtered QSOs by lotw_qsl_sent for all non-LoTW export modes
• After uploading to LoTW, QSOs have lotw_qsl_sent='Y', so the old filter excluded them from the Clublog/eQSL grid combo box, leaving it empty and preventing upload
• Now uses the correct field per service: clublog_qso_upload_status='M' for ClubLog, eqsl_qsl_sent='Q' for eQSL, qrzcom_qso_upload_status='M' for QRZ

Root cause

getGridsToBeSent() had this logic:

if ((_justModified) && (_em == ModeLotW))
    _query_justQueued = "lotw_qsl_sent='Q'";
else
    _query_justQueued = "((lotw_qsl_sent!='1') OR (lotw_qsl_sent IS NULL))";

When called from the Clublog or eQSL upload dialog (_justModified=true, _em=ModeClubLog/ModeEQSL), it fell into the else branch and still filtered by lotw_qsl_sent. After uploading to LoTW those records have lotw_qsl_sent='Y', so the query returned no grids → empty dialog.

The fix mirrors the pattern already used in getQueryJustModifiedString(), switching on ExportMode to pick the right field for each service.

Test plan

• Add a QSO with CLUBLOG_QSO_UPLOAD_STATUS=M and LOTW_QSL_SENT=Q
• Upload the QSO to LoTW (sets LOTW_QSL_SENT=Y)
• Open "Upload queued QSOs to ClubLog" — station callsign and grid locator should now populate correctly and the QSO should appear in the list
• Repeat for eQSL and QRZ upload dialogs
