CLAUDE: Fix DraftData validation errors for optional channel IDs

Fix Pydantic validation errors when channel IDs are not configured:

Issue:
- result_channel_id and ping_channel_id were required fields
- Database may not have these values configured yet
- /draft-admin info command failed with validation errors

Fixes:
1. models/draft_data.py:
   - Make result_channel_id and ping_channel_id Optional[int]
   - Update validator to handle None values
   - Prevents validation errors on missing channel data

2. views/draft_views.py:
   - Handle None channel IDs in admin info embed
   - Display "Not configured" instead of invalid channel mentions
   - Prevents formatting errors when channels not set

Testing:
- Validated model accepts None for channel IDs
- Validated model accepts int for channel IDs
- Validated model converts string channel IDs to int
- All validation tests pass

This allows draft system to work before channels are configured
via /draft-admin channels command.
