QRegExp → QRegularExpression migration complete

Migrated all remaining QRegExp usage to QRegularExpression for Qt6 compatibility:

- Lts/Viewer/SituationMap/SymbologyImpl/symbol_dictionary_impl.cpp
  - Changed helper functions to use QRegularExpression::match().hasMatch()
  - Updated inline regex validation

- Lts/Plugins/PlanEditor/mil2525d_to_mil2525c.cpp
  - Fixed m_sidcQuery.exactMatch() → match().hasMatch()

- Lts/Plugins/PresentationManagement/Gui/Script/ScriptTimelineEditor/pre_script_dialog.cpp
  - Video file pattern matching migrated

- Lts/Proxies/TrainingAreaBase/Plugins/Nmea/nmea_handler_rx.cpp
  - NMEA message parsing with QRegularExpression

- Lts/Proxies/TrainingAreaBaseOC/handler_aes_data.cpp
  - AES data handler regex patterns migrated

- Lts/Services/AudioVideoManagement/stream_name_mapping.*
  - Stream name validation patterns

- Lts/Services/NmeaManagement/nmea_handler.cpp
  - NMEA handler regex patterns

- Lts/Viewer/SituationMap/Symbology/sidc_builder_base.cpp, sidc_codec.cpp
  - SIDC code validation patterns

- Test files updated for compilation

All QRegExp::exactMatch() calls replaced with QRegularExpression::match().hasMatch()
All QRegExp::cap(n) calls replaced with QRegularExpressionMatch::captured(n)
