fix: resolve all ESLint errors

- droidRelayService: add missing keyId variable declaration
- quotaCardService: use object destructuring for actualDeducted
- apiKeyService: remove unused variables and duplicate requires
- redis: remove shadowed logger/config requires
- unifiedGeminiScheduler: rename isActive param to avoid shadow
- commonHelper: add comments to empty catch blocks
- testPayloadHelper: prefix unused model param with underscore
