This commit removes the _calculate_self_scattering_correction function in
polaris_algs that is now covered by the CalculateSelfScatteringCorrection algorithm.

Re #27445

This commit creates a documentation rst file for MergeWorkspacesWithLimits
Along with the workflow diagram dot file. It also makes changes to the
MergeWorkspacesWithLimits algorithm to include a name and version that
is required by the documentation compiler.

This commit corrects a mistake in the property names for
CalcuateSelfScatteringCorrection.

This commit removes the commented out command to the
_merge_workspaces_with_limits function in polaris_algs in place of the workflow
algorithm.

This commit creates a blank rst file that will later contain the documentation for
CalculateSelfScatteringCorrection.

Re #27445

This commit creates a workflow algorithm named MergeWorkspacesWithLimits
that handles the merging of the focused workspaces in the polaris scripts.

This commit removes a duplicated _load_qlims function in polaris_algs mistakenly added in commit 4c588e.

This commit adds a black line at the end of the CalculateSelfScatteringCorrection algorithm.

Re #27445

This commit creates a workflow algorithm named CalculateSelfScatteringCorrection
that handles the calculate of the placzek self scattering correction to be subtracted
from the focused data in the polaris scripts.

Re #27445

This commit fixes missed line that would allow the index for the max range spectra
to be updated

Re #27444

This commit moves the code for reading the supplies q limits into its own function.
This also fixes a bug that cause an error when trying to read a lim file path that is in
a unicode format.

Re #27444

This commit adds a catch for if the workspaces or q_lims file have an infinite range

to be updated

Re #27444

This commit changes the previously hard coded index for matching spectra to
instead use the workspace with the larges range of x values as these produces the
smoothest match around the edges of the workspaces data.

Re #27444

This commit changes the usage of ConjoinSpectra to a loop using ConjoinWorkspace.
This is done because using ConjoinSpectra the focused workspace can have a
mismatch between specnumbers and index

Re #27444

previous filename used POL+run_number, now loads
POLARIS+run_number_.nxs

this commit cehckes the position of monitor detectors for extraction
before use with FitIncidentSpectrum in _calculate_self_scattering_correction

as q_lims is a required paramiter for the function it would raise an error
if trying to run without it, even when it is not needed for merge_Banks=false
this change automaticaly sets q_lims to none when none is given as kwargs

CalculatePlaczekSelfScattering outputs non-distrebution workspace
correction to CalculatePlaczekSelfScattering algorithm and POLARIS
_generate_grouped_ts_pdf function makes self scattering correction
to the correct order of magnetude after processing

CalculatePlaczekSelfScattering outputs non-distrebution workspace
correction to CalculatePlaczekSelfScattering algorithm and POLARIS
_generate_grouped_ts_pdf function makes self scattering correction
to the correct order of magnetude after processing

Placzek correction will be covered in issue #26986

Also fixes FitIncidentSpectrum.py and CalculatePlaczekSelfScattering so
that output workspace has same x units

this calculates a background based on the mean value of the flatist 5 percent
of the fitted incident spectrum, based on the first derivitive
