refactor: simplify Channel initialization and lambda expressions

- Replace function references with lambdas for lazy `Channel` initialization in `UpdateTitleUseCase`, `DeleteNoteUseCase`, and `SaveNoteUseCase`.
- Remove redundant `return@firstNotNullOf` label in `IosCipherUtils` to simplify the database path resolution lambda.
