In `@for` blocks, tracking callable objects by reference (e.g. signal forms `FieldTree`, signals, or custom callable objects) is a valid pattern when tracking by object identity. Previously, `UninvokedTrackFunctionCheck` (NG8115) flagged any property read whose type has call signatures, regardless of whether the target was an actual track function expecting arguments or a method reference.
This commit updates `UninvokedTrackFunctionCheck` to only emit a diagnostic when the target expression has call signatures that declare parameters (functions/methods expecting arguments like `(item)` or `(index, item)`) or is a method declaration. Callable objects without parameters accessed as properties are now recognized as tracked values and not flagged as uninvoked track functions.
