fix(guardrails): harden Akto MCP detection, keep AGENTIC default, block unmappable masking
- MCP handling trusts the logger's call type, so request body keys can't skip the prompt check - context_source defaults to AGENTIC, as before - masking that also hits text we can't write back now blocks - move tests to tests/unit and rename attachments.py to akto_attachments.py - regenerate the OpenAPI snapshot and dashboard types
