Add WAF-like functionality to mitmproxy for protecting services exposed
to the internet. Incoming WAN traffic is redirected through mitmproxy
for threat detection before reaching backend services.
Features:
- WAN protection mode with nftables rules for incoming traffic
- Enhanced bot scanner detection with 50+ scanner signatures
- Behavioral detection for config/admin/backup/shell hunting
- CrowdSec integration with new scenarios for bot scanners
- LuCI interface for WAN protection configuration
- DPI mirror mode support (secondary feature)
New CrowdSec scenarios:
- secubox/mitmproxy-botscan: Detect automated reconnaissance
- secubox/mitmproxy-shell-hunter: Detect shell/backdoor hunting
- secubox/mitmproxy-config-hunter: Detect credential file hunting
- secubox/mitmproxy-suspicious-ua: Detect suspicious user agents

- Change analytics addon to write threats to /data/threats.log (bind-mounted to host)
- Add CrowdSec acquisition config to read from /srv/mitmproxy/threats.log
- Add parser for mitmproxy JSON threat logs with source_ip in Meta
- Add scenarios for web attacks, scanners, SSRF, and CVE exploits
- Update RPCD to read alerts from host-visible path without lxc-attach
This enables automatic IP banning when mitmproxy detects:
- SQL injection, XSS, command injection (capacity: 3, ban: 15m)
- Path traversal, XXE, LDAP injection, Log4Shell
- Aggressive web scanning (capacity: 10, ban: 10m)
- SSRF attempts from external IPs (capacity: 5, ban: 10m)
- Known CVE exploits (immediate trigger, ban: 30m)

- Change evt.Line contains -> evt.Line.Raw contains in parsers
(pipeline.Line type requires .Raw accessor for string operations)
- Remove invalid filter: field from acquisition configs
(filter belongs in parsers, not acquisition files)
Fixes CrowdSec v1.7.6 startup failures.
