… and maintainability
### What is this PR for?
This PR refactors the `InfluxDBInterpreter.class` to improve code readability, maintainability, and adherence to modern Java practices, without altering its runtime behavior or core logic.
- Key changes include:
- Renamed getInfluxDBClient() to better reflect its purpose (e.g., getQueryApi()), improving semantic clarity.
- Removed unnecessary code
- (e.g., InterpreterContext) from methods where they are unused.
- Throwing exceptions from methods like open(), close(), cancel(), getFormType(), and getProgress() where exceptions are not thrown.
- Extracted long nested logic blocks in `internalInterpret()` into smaller, well-named private methods.
- Replaced imperative loops with Stream operations for collection processing.
These changes aim to make the codebase more modular, clean by reducing boilerplate code, and approachable for future contributors and reviewers.
