Description

forecast-inference is moving to read all site data (including tilt/orientation) directly from the Data Platform instead of the site database. DP has no native field for these — they're a property of the specific energy source, not the underlying geometry — so this PR writes them into each location's metadata on create/update (confirmed to land on sources_history, not geometries: verified via source-code trace of the DP server and a live behavioral test — renaming a location leaves its metadata untouched).

create_location()/update_location() in dataplatform_client.py now accept optional tilt/orientation, and main.py's site create/edit routes pass them through. update_location() also gains an opt-in raise_on_error flag (default False, live API behavior unchanged) so batch tooling can detect real failures instead of the existing swallow-and-log default silently reporting success.

⚠️ Requires a one-time backfill before this is useful for existing sites — this only writes tilt/orientation going forward. Run scripts/backfill_dp_tilt_orientation.py (new in this PR) against the target environment to populate DP metadata for sites that predate this change:

Tests:

1. This one is tested against the dev dataplatform
2. Ran script

DB_URL=... DATA_PLATFORM_HOST=... DATA_PLATFORM_PORT=... \
    python scripts/backfill_dp_tilt_orientation.py --apply
