fix: handle TargetClosedError gracefully and improve parameter verification

- initialization: catch TargetClosedError during page init, skip gracefully
- initialization/model_management: downgrade noisy warnings to DEBUG
- _set_parameter_with_retry: is_equal extracts float from strings like 'user:1.0'
- _set_parameter_with_retry: input_value timeout 2s -> 5s
