docs: add visualization preview at top of RasterFlow model notebooks

[pdarringer]

Summary

Adds a "Preview: model inputs and outputs" markdown cell to the top of each RasterFlow ML model notebook (after the model description, before AOI selection) so readers can preview the inputs and outputs interactively before running any code.

Each cell contains a short description, a bulleted list of layers in the map, and a link to a pre-built viz.wherobots.com URL that opens the AOI with all layers loaded.

We use a plain link rather than an embedded <iframe> because JupyterLab and VS Code strip raw HTML iframes from rendered markdown cells.

Files changed

• Analyzing_Data/RasterFlow_CHM.ipynb — Nashua NH: input mosaic + model output raster
• Analyzing_Data/RasterFlow_Chesapeake.ipynb — Montgomery County MD: mosaic + raster + vectors + PMTiles
• Analyzing_Data/RasterFlow_FTW.ipynb — Haskell County KS: planting + harvest mosaics + raster + vectors + PMTiles
• Analyzing_Data/RasterFlow_SAM3.ipynb — Marion County OR: mosaic + vectors + PMTiles (geometry inference model, no raster)
• Analyzing_Data/RasterFlow_Tile2Net.ipynb — College Park MD: mosaic + raster + vectors + PMTiles

Test plan

• Open each notebook in JupyterLab / VS Code and confirm the Preview cell renders cleanly
• Click the link in each notebook and verify the map loads with all layers visible

Pull request overview

This PR improves the RasterFlow example notebooks by adding an early “Preview: model inputs and outputs” markdown section so readers can open a preconfigured viz.wherobots.com map to inspect the notebook’s example AOI inputs/outputs before running any code.

Changes:

• Added a standardized “Preview: model inputs and outputs” markdown cell near the top of each RasterFlow model notebook.
• Included a short layer list plus a deep link to viz.wherobots.com that loads the relevant imagery/model outputs/vectors/PMTiles for the example AOI.

File	Description
Analyzing_Data/RasterFlow_CHM.ipynb	Adds preview cell + viz link for CHM example (needs wording adjustment re: vectors).

Analyzing_Data/RasterFlow_FTW.ipynb	Adds preview cell + viz link covering planting/harvest mosaics + outputs.
Analyzing_Data/RasterFlow_SAM3.ipynb	Adds preview cell + viz link (needs wording/AOI consistency fixes).
Analyzing_Data/RasterFlow_Tile2Net.ipynb	Adds preview cell + viz link for Tile2Net inputs/outputs + vectors/PMTiles.

• The preview map link points to Marion County, OR (see URL title/lat-lng), but the AOI section immediately below still uses College Park, MD (wkls.us.md.collegepark). To avoid confusing readers, please make the preview link and the notebook’s actual example AOI consistent (either update the link or update the AOI/code).

One copy-paste boilerplate slip in the SAM3 notebook — it references a 'raster model output' that doesn't exist for this geometry-only model. The other four notebooks look clean.
