Add Delineate Hydrologic Features from Point Workflow

[Sonia-96]

Add a SelectPointRWS(SpatialInputRWS) work flow step for Delineate Hydrologic Features from Point Workflow. The user needs to pick a point that has low elevation within the raster:

1. Show the Input Raster, which is usually a DEM, and its legend on the map, so the user knows the elevation change of the area.

2. Add a tooltip to show the elevation when the user hover over the Input Raster layer

3. The user can only draw one point on the map. If they draw a new one, the old one will be removed automatically

4. Data validation: the point must be within the raster

Output files look like as follows:

Merge conflicts resolved. The only conflict was in pyproject.toml where both branches added new workflow entries — kept both delineate_hydrologic_features_from_point and generate_tin.
