Memory ownership and lifecycle management between FORM and Phlex #392
Description
Proposed Fixes (Follow up from PR#379)
In form/root_storage/root_tbranch_container.cpp: Add a reset for the branch address to prevent invalid references.
In form/form_source.cpp: Update the logic to either free the memory after the copy or, preferably, transfer the pointer ownership to the Phlex framework.
Safety Check: Ensure memory is freed even in cases where the data is read but not successfully passed to Phlex.
