feat: Remove Rule column from findings table for cleaner display

Removes the Rule column from findings table to simplify the view and reduce
redundancy with the Message column. Rule ID is still available in:
- Detailed finding view (ff finding show <run-id> --id <finding-id>)
- By-rule grouping command (ff findings by-rule <run-id> --rule <rule-id>)

Changes:
- Removed 'Rule' column from table structure
- Removed rule_text extraction and styling logic
- Expanded Message column from 35 to 50 chars (more space available)
- Expanded Location column from 18 to 20 chars
- Table now shows: ID | Severity | Message | Found By | Location

Benefits:
- Cleaner, more scannable table
- Message column has more room to show details
- Less visual clutter while maintaining all functionality
