fix: replace deprecated datetime.utcnow() with timezone-aware datetime.now(timezone.utc) (#816)

Browse source 
Python 3.14 deprecates datetime.utcnow(). Replace all 9 occurrences with
datetime.now(timezone.utc) and normalize the output to preserve the existing
ISO-8601 "Z"-suffixed format so downstream parsers are unaffected.

Fixes #814
