fix(common-config): reset initialization flag when preset changes

The common config checkbox was only auto-enabled for the first preset
(custom) because hasInitializedNewMode ref was permanently locked to
true after first initialization.

Add selectedPresetId parameter to all three common config hooks and
reset the initialization flag when preset changes, allowing the
initialization logic to re-run for each preset switch.
