Refactor: improve null safety, optimize dropdown handling, and enhance UI alignment

- Added null safety checks in `MainComponent` to prevent potential crashes during room selection. - Replaced `ExposedDropdownMenuBox` with a custom `DropdownMenu` implementation for streamlined organizer selection. - Adjusted dropdown menu width dynamically based on `TextField` size. - Fixed UI inconsistencies in `EventDurationView` by using `stringResource` for all string references. - Updated `UpdateEventComponent` to expand dropdown automatically when filtering organizers.
