CAS-14622: Fix out-of-bounds MPI segmentation faults in BriggsCubeWeightor
The SynthesisImager uses BriggsCubeWeightor to compute weights for the image cube. During distributed MPI execution (`ncores > 1`), the output cube's spectral axis is partitioned across multiple nodes into smaller local subcubes.
When evaluating MS data channels, `GridFT::channelMap` maps the visibilities' frequencies into the local subcube's channel indices. If an MS contains dataset frequencies (e.g., from large Doppler swings or wide ephemeris velocity changes) that land *above* the local MPI subcube's maximum channel, `channelMap` returns an index exceeding the local array bounds.
Previously, BriggsCubeWeightor only checked the lower bound (`chanMap(chn) > -1`) before using the calculated index to access `wgtDensity` and the `f2_p`/`d2_p` arrays. Accessing these arrays with indices belonging to higher MPI partitions resulted in unconstrained out-of-bounds memory accesses, causing silent heap corruption or explicit Segmentation Faults, heavily dependent on the MPI slicing and dataset footprint.
This commit resolves the issue by introducing strict upper-bound channel footprint constraints (`chanMap(chn) < shape()[3]`) in both `weightUniform` and `getWeightUniform`. Data channels that mathematically fall outside the upper bounds of the local MPI partition are now securely ignored. -

CAS-14622: Fix ncores-dependent tclean segmentation fault in `BriggsCubeWeightor`
The SynthesisImager uses `BriggsCubeWeightor` to compute weights for the image cube. During this calculation, `BriggsCubeWeightor::cube2Matrix` extracts raw storage pointers `pcube` and `pflags` from `casacore::Array::getStorage(deleteIt)`.
Previously, the code incremented these exact pointers (`*pflags = *pcube++`) during array traversal. At the end of the function, the incremented pointers were passed directly to `freeStorage()` and `putStorage()`.
When array memory isn't contiguous (which occurs when data is sliced across MPI ranks), `getStorage()` allocates a temporary buffer and sets `deleteIt = true`. Passing the shifted pointer into `freeStorage()` invokes `delete[]` on an invalid memory address, causing heap corruption and a Segmentation fault randomly depending on the data slicing.
This commit resolves the issue by securely caching the original pointers returned from `getStorage` into distinct variables. The traversal loops now use separate copies of these pointers, enabling the original allocation addresses to be correctly evaluated and freed by `freeStorage()` and `putStorage()`. -

CAS-13818 : Fix mask cache conflict on tclean restart
As documented, the fix for the original issue triggered a mask cache
conflict on restart. In the end the fix turned out to be fairly simple -
check if the mask exists and is valid, and do not touch it if it is.
So in the first instance, when the mask does not exist, it will do the
right thing. And it will not try to do anything on the restart either.
It ended up being a simple inversion of the original logic, with
appropriate traps in place so it works for both the original bug and the
derived bug. -

CAS-13818 : Disable test_imgval_startmodel_axesmismatch on MacOS
Added a skip to test_imgval_startmodel_axesmismatch in test_task_deconvolve for
MacOS. This test fails for unknown reasons, unrelated to the code on this
branch.
The failure and solution are being investigated on CAS-14117 and will be
re-enabled on that ticket. -

CAS-13818 : Fix for failing test
The previous commit fixed the issue from the parent ticket (no mask for
multi-stokes MT-MFS images) in the wrong location, causing a single tclean test
to fail. This commit moves the fix to the right spot, i.e., into
SDAlgorithMSMFS::restore which works.
All the tclean + deconvolve tests now pass locally. -

CAS-13818 : Fix for image.tt0 pb mask
Fixed the issue, the full Stokes MT-MFS restored images now have the PB mask
included correctly. This has been tested with the script provided to reproduce
the original issue.
