Purge legacy is_grid_point=true rows from hrrr_profiles
The grid worker stopped writing HRRR profiles to the DB on April 14
when the forecast grid moved to /data/scores binary files, but the
24/72h-windowed prune left every is_grid_point=true row older than
72 hours sitting in the table (billions of rows across every
partition back to 2016, ~90% of the 146 GB table size). Nothing
reads them anymore.

Replace prune_old_grid_profiles/0 with purge_grid_point_profiles/0,
which walks every hrrr_profiles partition directly and deletes
is_grid_point=true rows regardless of age. Per-partition DELETEs
avoid a parent-table full scan. QSO-linked rows (is_grid_point=false)
are untouched — those still back contact enrichment and /path.

Call the new purge from the grid worker's end-of-chain hook so any
grid-point row that somehow slips back in gets cleaned up within the
next hour. Add `mix hrrr.purge_grid_points` for a one-shot historical
cleanup.
