test: Remove unnecessary catch blocks from Tcl tests across all modules

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.
