refactor: complete SOLID fixes + RAII guards + enhanced test assertions

ISP (Interface Segregation Principle):
  - Add JobStatusStore trait for database persistence
  - Implement PgJobStatusStore for PostgreSQL
  - Add MockJobStatusStore for unit testing
  - IngestWorker::with_job_store() enables dependency injection
  - Job status updates now via trait (testable, mockable)

Resource Management (RAII):
  - Add PortForwardGuard struct with Drop impl
  - Ensures port-forward process killed even if test panics
  - Prevents resource leaks in integration tests

Test Assertions (Verification):
  - Enhanced unit tests verify entity names, not just counts
  - Verify edges connect correct entity pairs
  - Verify both source and target entities exist
  - Batch processing verifies expected entities extracted
  - Entity deduplication test across multiple records

All 9 issues now fixed:
  ✅ DRY: Removed wrapper function
  ✅ CRAP: Extracted save_*_with_logging() helpers
  ✅ OCP: Added JobStatus enum
  ✅ SRP: Real-time logging, no error accumulation
  ✅ ISP: JobStatusStore trait + mocking
  ✅ Logging: IngestLogContext struct
  ✅ RAII: PortForwardGuard for cleanup
  ✅ Error handling: Real-time logging at point of failure
  ✅ Test assertions: Verify names + connections

Verification: cargo check -p mem-cli ✓

+//! Unit test: Ingest pipeline with detailed error logging and enhanced assertions
+//!
+//! Tests extraction pipeline in isolation without requiring HTTP server or embeddings.
+//! Useful for debugging extraction errors.
+//!
+//! Features:
+//! - Verify extracted entity names (not just count)
+//! - Verify edge connections between entities
+//! - Detailed error logging
+//!
+//! Usage:
+//! ```
+//! RUST_LOG=debug,mem_ingest=debug cargo test --test unit_ingest_logging -- --nocapture
