   ## What changes are proposed in this pull request?
   
   Adds SVG visual illustrations to the remaining function documentation pages, 
covering 5 categories in a single phase:
   
   ### Categories covered
   
   | Category | Functions | SVGs |
   |----------|-----------|------|
   | Linear Referencing | ST_LineInterpolatePoint, ST_LineLocatePoint, 
ST_LineSubstring, ST_AddMeasure, ST_InterpolatePoint, ST_IsValidTrajectory, 
ST_LocateAlong | 7 |
   | Bounding Box | ST_Envelope, ST_BoundingDiagonal, ST_Expand, ST_XMax, 
ST_XMin, ST_YMax, ST_YMin, ST_ZMax, ST_ZMin, ST_MMax, ST_MMin | 11 |
   | Aggregate | ST_Collect_Agg, ST_Union_Agg, ST_Intersection_Agg, 
ST_Envelope_Agg | 4 |
   | Clustering | ST_DBSCAN, ST_LocalOutlierFactor | 2 |
   | Address | ExpandAddress, ParseAddress | 2 |
   | **Total** | | **26** |
   
   ### Files changed
   
   - **26 new SVG files** in `docs/image/`
   - **62 modified doc files** across SQL, Flink, and Snowflake variants
   
   ### Visualization styles
   
   - **Linear Referencing**: Line with interpolation point/fraction markers and 
substring highlights
   - **Bounding Box**: Geometry with bounding envelope, diagonal, or 
axis-aligned min/max indicators
   - **Aggregate**: Multiple input geometries with arrow showing aggregation 
into result
   - **Clustering**: Point cloud with colored cluster assignments (DBSCAN) or 
LOF score shading
   - **Address**: Text-based diagrams showing address expansion/parsing
   
   ### Notes
   
   - Not all functions exist in all variants (e.g., Clustering and Address are 
SQL-only, some Linear Referencing functions are missing from Snowflake)
   - Each image is placed above the Format line with appropriate relative paths 
per variant
   - Part of the ongoing effort to add visuals to all Sedona function docs 
(issue #2678)
