Fix missing API key extraction in standalone verify flow

CRITICAL BUG: When running --verify-email-code separately (not during registration),
the script was not extracting the API key from the verification response.

Problem:
- Registration flow had API key extraction code (line 387-393)
- Standalone verify flow was missing it (line 445)
- API key returned by API but not saved to config

Solution:
- Added API key extraction to standalone verification flow
- Now both flows extract and save the API key properly
