Add WFIGS_Incident_Locations_Current point layer (IRWIN superset, ~6 ID fires)
alongside the existing perimeter layer (~2 ID fires). Fires are merged by IrwinID:
point layer is the authoritative superset, perimeter layer supplies polygon
geometry and validated acreage when available. Point-only fires surface with
lat/lon from the point geometry and no polygon. cold-start silent-seed path is
unchanged (first-poll batch is always silent regardless of source). Perimeter
fetch failure falls back to perimeter-only stubs; point fetch failure falls back
to perimeter-only; both failing bumps the consecutive error counter. county is
now populated from POOCounty on the point layer. Five off-air unit tests cover:
T1 merge-dedup, T2 point-only-new, T3 perimeter-geom-preferred, T4 cold-start
silent-seed 6 fires, T5 FIRMS _get_known_fires attribution.
No changes to store.py, gating/fire.py, schema, or coverage.
