feat(dpi-dual): Add WAF auto-ban tuning system
- UCI config: Add scoring section with event weights, sensitivity presets,
whitelist, and decay options
- dpi-correlator: Load scoring weights from UCI, apply sensitivity
multipliers, check whitelist before auto-ban, periodic reputation decay
- CLI: New 'tune', 'whitelist', 'decay' commands for runtime configuration
- RPCD: 6 new methods - get_tuning, set_tuning, whitelist_add/remove/list,
reset_reputation
- ACL: Added permissions for new tuning methods
Sensitivity presets:
- low (0.7x) - fewer false positives
- medium (1.0x) - balanced (default)
- high (1.3x) - aggressive detection
