ENH: radiometerProbes: new function object to monitor radiative heat flux at internal points

The radiometer probes enable measurement of incident radiative heat flux
at arbitrary internal points within the domain, useful for radiation sensor
simulation and heat transfer analysis in participating media applications.

 Note
-   If the \c sigma entry is present, the electrical conductivity is specified
-   as a function of temperature using a \c Function1 type, otherwise
-   the \c sigma field will be read from file.

-   \table
-     Field   | Scoped names              | Scoped names (old)
-     V       | \<scope\>:V (suffix)      | \<scope\>:V_ + regionName
-     sigma   | \<scope\>:sigma (suffix)  | \<scope\>:sigma_ + regionName
-   \endtable
-
-   It is possible to replicate the older naming by specifying
-   the \c suffixing to ('_' + regionName).
+  - \c anisotropicElectricalConductivity=true enables
+  anisotropic (tensorial) electrical conductivity.
+  - \c anisotropicElectricalConductivity=false enables
+  isotropic (scalar) electrical conductivity.
+  - The electrical conductivity can be specified using either:
+    - If the \c sigma entry is present the electrical conductivity is specified
+    as a function of temperature using a \c Function1 type.
+    - If not present the \c sigma field will be read from file.
+    - If the \c anisotropicElectricalConductivity flag is set to \c true,

-Note
-    The \c suffixing parameter is a hint that individual models may use
-    when automatically generating variable names internally. For example,
-    a model \em may provide ("T" + suffixing) and ("q" + suffixing)
-    as its default names temperature and flux fields, respectively.
-    If the user specifies \c suffixing = "_foo", those \em default names
-    would then become "T_foo" and "q_foo", respectively.
-    Suffixing (true|false|none|default|...) currently selects between
-    no suffix and ('_'+region).

 Description
-    Set of locations to sample at patches
+    Probes the specified points on specified patches. The points get snapped
+    onto the nearest point on the nearest face of the specified patch, and the
+    sampling is actioned on the snapped locations.
 
-    Call write() to sample and write files.
-    - find nearest location on nearest face
-    - update *this with location (so header contains 'snapped' locations
-    - use *this as the sampling location
-
-    Example of function object specification:
+Usage

+Class
+    Foam::internalProber
+
+Description
+    A utility class for probing field values at specified point locations
+    within an \c fvMesh.
+
+    The \c internalProber stores a list of 3D point coordinates and
+    determines the corresponding mesh elements (cells or faces) that contain
+    these points. It provides methods to sample volume or surface fields at
+    the stored locations, with support for fixed or mesh-moving point
+    coordinates.
+
+    Features include:
+      - Reading probe locations and settings from a dictionary
+      - Support for fixed or moving locations (for dynamic mesh cases)
+      - Optional inclusion of points that lie outside of the mesh domain
+      - Selection of interpolation/sampling schemes for fixed locations
+      - Sampling of volume and surface fields by name or by direct reference
+      - Automatic update of element mapping when the mesh changes or moves

+Class
+    Foam::patchProber
+
+Description
+    Utility class for probing specified points on user-selected boundary
+    patches. The input points are projected onto the nearest point of the
+    nearest face on the specified patch, ensuring sampling occurs at valid
+    patch locations.
+
+    The patchProber enables sampling of both volume and surface fields
+    at these snapped locations. Patch selection is controlled via patch names or
+    indices, and the class provides runtime selection and dictionary-driven
+    configuration.
+
+    Typical usage involves specifying patch names and probe locations in a
+    dictionary, after which the class manages the mapping and sampling
+    operations.

 Description
-    Set of locations to sample.
+    Function object to sample fields at specified internal-mesh locations and
+    write to file.
 
-    Call write() to sample and write files.

-    Example of function object specification:
+Usage
+    Minimal example by using \c system/controlDict.functions:
     \verbatim
