refactor(global-search, environment): streamline environment retrieval with new query method

- Replaced the inline query for fetching environments in GlobalSearch with a new static method `ownedByCurrentTeam` in the Environment model, enhancing code readability and maintainability.
- This change simplifies the logic for retrieving environments associated with the current team, promoting better organization of query logic within the model.
