Adding some satellite tools: eo-predictor, historical-satellite, search-eo, stac utilities

Hi there,
I never took the time to thank the whole bellingcat team and contributors for this impressive toolkit resource.

Just wanted to mention some tools that might be interesting to include in the satellite section:
- Similar to [OrbTrack](https://bellingcat.gitbook.io/toolkit/more/all-tools/orbtrack): development-seed vibe-coded [devseed/eo-predictor](https://developmentseed.org/eo-predictor/)
- [Iconem/Historical-Satellite](https://historical-satellite.iconem.com/#3/10/0) comparison of public satellite/aerial basemaps. A bit rough at the edges, update upcoming ([mockup](https://v0-historical-sat-ui-mockup-design.vercel.app/)), [open-source](https://github.com/iconem/historical-satellite/)
- [Iconem/SearchEO](https://search-eo-imagery.iconem.com), aggregator of commercial satellite imagery aggregators (Up42, SkyFi, EOS, Skywatch, Arlula, ApolloMapping etc), [open-source](https://github.com/Iconem/search-satellite-imagery/) as well
- STAC utilities like [devseed/stac-map](https://developmentseed.org/stac-map/), [element84/earth-search](https://console.earth-search.aws.element84.com/) and [radiantearth/stac-browser](https://radiantearth.github.io/stac-browser/) to search open-data collections like landsat, sentinel, open-aerial-map, gathered into a single point-of-entry, all open-source
- Similar to [UNOSAT-Analyses](https://bellingcat.gitbook.io/toolkit/more/all-tools/unosat-analyses#description): emergency mapping services like [Copernicus-EMS](https://mapping.emergency.copernicus.eu/activations/), [Disaster-Charter](https://disasterscharter.org/fr), [HOT-OSM](https://tasks.hotosm.org/), Humanitarian Data Exchange [HDX](https://data.humdata.org/)

Some might benefit from a dedicated page showcasing the tool features, some other might only be grouped into a dedicated list.
Hope this helps!
In case you want me to contribute some of these when I've got the time, would love some pointers.

Start by reviewing the toolkit's satellite section and the existing entries such as OrbTrack and UNOSAT-Analyses. Decide which suggested tools belong in individual pages or a grouped list, then add the selected links and descriptions; done means the satellite resources are organized consistently with the existing section.
