refactor(eslint): change unused vars rule to error and update error handling in services

- Update ESLint configuration to set `@typescript-eslint/no-unused-vars` from 'warn' to 'error' for stricter linting.
- Refactor error handling in various services to omit error variable in catch blocks for cleaner code.
