refactor: fix remaining code review issues on kabi-use

- _get_client: remove useless try/except that re-raised same error
- verify_cookies: increase timeout from 3s to 5s
- fetch_user: use _deep_get for URL extraction (consistent with
  _parse_user_result)
- formatter: remove no-op tweets_to_json wrapper and unused import
- _as_int/_as_float: filter.py now imports from config.py (dedup)
- CLI read commands: extract _fetch_and_display() to dedup
  favorite/search/likes/list_timeline
- _write_action: move load_config inside try block
- auth.py: add PEP 8 blank line after logger
