[grade=A] P1-8: replace 66 console.* calls across 6 remaining files with structured logger

Files changed:
- src/security/crypto-utils.js: 16 calls → log tagged 'crypto'
- src/security/docker-security.js: 15 calls → log tagged 'security'
- src/managers/port-lock-manager.js: 16 calls → log tagged 'portlock'
- src/docker/self-updater.js: 10 calls → log tagged 'updater'
- src/security/event-workers.js: 5 calls → log tagged 'events'
- src/security/keychain-manager.js: 4 calls → log tagged 'keychain'

Fixed 2 bugs found during sweep:
- self-updater.js:161 — arrow expression body had trailing semicolon (SyntaxError)
- port-lock-manager.js:137 — log.error referenced 'port' var out of scope (ReferenceError)

1539/1539 Jest tests pass. All ESLint warnings pre-existing (0 new).
