Advertise GTiff batch outputs as Cloud-Optimized GeoTIFF media type

[Copilot]

Batch job results were exposing COG files with the generic GeoTIFF media type (image/tiff; application=geotiff), which causes downstream clients to treat them as non-cloud-optimized rasters. This change aligns GTiff result metadata with COG semantics by emitting the COG profile media type.

• Media type mapping update

  • Updated IOFORMATS so GTiff resolves to:
    • image/tiff; application=geotiff; profile=cloud-optimized
  • This ensures response/content typing and STAC asset typing consistently advertise cloud-optimized GeoTIFF for GTiff outputs.

• Batch asset metadata consistency

  • Updated dummy backend batch-result asset metadata for .tiff outputs to use the same COG media type.
  • Keeps API-level job result payloads and download endpoints aligned with format mapping behavior.

• Expectation alignment in tests

  • Updated GTiff/GeoTIFF MIME-type assertions in focused test coverage (ioformats, execute response headers, and batch job result/view assertions) to the COG media type.

Example of the effective change:

# Before
FormatInfo("GTiff", "image/tiff; application=geotiff", extension="geotiff")

# After
FormatInfo("GTiff", "image/tiff; application=geotiff; profile=cloud-optimized", extension="geotiff")

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
