fix: ZIP rep lookup — handle GEOID20 for 119th Congress TIGERweb layers

Browse Source 
The 119th Congressional Districts layer uses 2020 Census vintage field
names (GEOID20, STATEFP20, CD119FP) instead of GEOID. The GEOID check
was silently falling through; added GEOID20 fallback, isdigit() guard,
try/except on CD field parsing, and debug logging of unparseable layers.
