Make alarm clustering deterministic and harden FRP handling

Make fire-detection clustering independent of input row order while
preserving the existing non-transitive, seed-based grouping semantics.

Instead of building transitive connected components, select the next
cluster seed deterministically from the remaining detection with the
highest finite FRP and group detections within the configured spatial
threshold around that seed. This retains the established operational
behaviour while removing dependence on the original feature ordering.

Add regression coverage for order-independent clustering and preserve
the existing large-fire grouping behaviour.

Harden representative-detection selection for unexpected FRP values.
Positive finite FRP values continue to determine the representative
detection as before. If a collection contains only non-positive or
non-finite FRP values, fall back to the first detection and emit a
warning instead of failing with an uninitialized local variable.

Also raise an explicit error for an empty detection collection.
