Add grid data from Sumo using ri-cloud-api
Load Eclipse grid data (roff) from Sumo as RimReservoirGridEnsemble, one case per realization, with async fetch of grid properties per timestep.
- New: RiaSumoGrid (transport), RifReaderSumoGridProperty (lazy property reader), RimReservoirGridEnsembleSumo, RimRoffCaseSumo, and a "Create Reservoir Grid Ensemble" command.
- Shared grid: IJK dimensions compared before download; one RigMainGrid is reused across the ensemble when they match, each realization still parses its own ACTNUM before releasing geometry.
- Rename folders: Summary/Sumo -> Summary/Cloud, RimSumoDataSource -> Cloud/ (PDM keywords unchanged, old project files still load).
- UI: cloud data sources also shown in the 3D window's Data Sources dock.
- Fix: realizations no longer lost on project reload; realizations missing data are now reported instead of silently skipped.
Sumo data is loaded so the application stays responsive while it waits.
Run Sumo transfers on a dedicated thread
Split RiaSumoConnector into transport and data delegates
Load Sumo summary vectors concurrently and without waiting

* CMake: Remove dead CODE_HEADER_FILES variable
* CMake: Remove dead COMMAND_CODE_HEADER_FILES and COMMAND_MOC_SOURCE_FILES
* CMake: Remove dead MOC_SOURCE_FILES and FORM_FILES_CPP references
* CMake: Remove dead HEADER_FILES reference
* CMake: Delete unused CustomPCH.cmake superseded by target_precompile_headers
- set fields read only
- make sure custom case name is used in other UI items
- use two buttons to create data source and ensemble for selected cloud ensembles
