fix(memory-defense): correct displayed pattern count

[Sanderhoff-alt]

Summary

• Correct the documented Memory Defense regex pattern count from 44 to 45.
• Update the current docs, versioned 0.8 docs, release blog, docs reference copy, and control-plane locale strings.

Why

The built-in _REDACTION_PATTERNS list currently contains 45 entries, but several documentation and UI strings still described it as a 44-pattern set.

Validation

• Counted _REDACTION_PATTERNS from hindsight-api-slim/hindsight_api/extensions/memory_defense.py with a small AST script.
• Searched for remaining 44-pattern / 44 redaction patterns / 44 bundled patterns and control-plane Memory Defense 44 strings.
• Pre-commit hooks ran during commit; lint completed successfully.
