Remove bare catch blocks that silently swallowed errors instead of
properly testing them. Fix underlying issues revealed by catch removal
including wrong API calls ([$role name] on strings, invalid properties
like cell_leakage_power/is_register, nonexistent Tcl bindings) and
incorrect library names. Update golden .ok files to match new output.
