feat: Open Data Catalog explorer with server-side clip

[prbatero]

Add an Open Data Catalog side panel to the Create Image Layer page so analysts can browse open disaster imagery (Vantor/Maxar + Planet Open Data), preview it, and build an image layer without hunting for COG URLs.

Catalog UI (ui/src/Components/OpenDataCatalog/):

• Dynamic discovery + merge of every event across the Vantor S3 STAC and Planet Source-Cooperative STAC catalogs; framework-free module with a discoverEvents()/fetchEventCatalog() contract (swap-to-backend seam).
• Azure Maps footprints + TiTiler COG preview (works with no Azure Maps key); preview tile loading indicator.
• Add a scene to pre/post in one click with source-type + capture-date auto-fill; buttons are phase-scoped (pre->Pre, post->Post).
• Two-way map<->list selection: click a footprint to scroll/highlight/expand the list row; footprints stay clickable during preview.

Server-side clip AOI:

• Draw a box that sets a layer-level clipBbox ([w,s,e,n] EPSG:4326); imagery prep clips the pre/post mosaics via gdalwarp -te/-te_srs (GDAL reprojects the bounds). The catalog filters scenes overlapping the AOI and badges scenes that fully cover it, so pre/post share one AOI.
• Model ImageLayer.clipBbox + validate_clip_bbox; PutLayer validates/carries it; threaded through the imagery-prep config -> ImageryWorkflow -> mosaic_imagery. Verified end-to-end (output bounds match the drawn box).

Supporting fixes:

• Allow data.source.coop on the imagery allowlist (UI + hastelib) and route non-S3/Blob allowlisted hosts through the generic HTTP downloader, so Planet imagery downloads at prep time.
• Local dev proxy (docker/nginx.conf): TiTiler timeouts + client_max_body_size for chunk uploads.
• QUICKSTART: DOCKER_GID must be 0 on macOS Docker Desktop.

Azure Maps auth is unchanged (existing anonymous/AAD Client-ID flow).

Pull request overview

Adds an in-app Open Data Catalog explorer on the Create Image Layer flow, letting analysts discover/preview open disaster imagery (Vantor/Maxar + Planet Source Cooperative) and build image layers faster, including an optional server-side clip AOI applied during imagery prep.

Changes:

• Adds new Open Data Catalog UI (panel + list + Azure Maps footprints + TiTiler preview) and wires it into the Create Image Layer form (including scene-to-pre/post “add” + auto-fill).
• Introduces ImageLayer.clipBbox end-to-end (UI → PutLayer validation → imagery-prep config → GDAL mosaic clip).
• Expands imagery URL allowlist to include data.source.coop and routes non-S3/Blob allowlisted URLs through the generic HTTP downloader; updates local dev proxy settings/docs.
