fix(storm-intel): show CloudHail icon for ice-pellet/hail forecast codes

Tomorrow.io 7xxx codes are ice pellets, not snow — remapped from Snowflake
to CloudHail. Added hailRisk override so any day flagged as hail risk by
the API always renders the hail icon regardless of weatherCode. Also added
missing 6xxx (freezing rain) codes to the icon table.

Mock Sunday entry corrected to weatherCode 8000 (thunderstorm) — 7102 at
76°F made no meteorological sense.
