When allow_from is not configured, block all access by default
instead of allowing everyone. This prevents unauthorized access
when channels are enabled without explicit allow lists.
- Remove trailing whitespace and normalize blank lines
- Unify string quotes and line breaks for long lines
- Sort imports alphabetically across modules

sharing one session per channel. DM sessions are unchanged.
Added as a generic feature to also support if Feishu threads support

Follow-up to #864. Three f-string logger calls in base.py and dingtalk.py
were missed in the original sweep. These can cause KeyError if interpolated
values contain curly braces, since loguru interprets them as format placeholders.
- Update sender ID construction to prioritize user ID while maintaining username for allowlist compatibility.
- Improve allowlist checking in BaseChannel to support sender IDs with multiple parts separated by '|'.
