fix: filter dynamic OpenCode models by enabled status in model selector

The phase model selector was showing ALL discovered dynamic models regardless
of whether they were enabled in settings. Now it filters dynamic models by
enabledDynamicModelIds, matching the behavior of Cursor models and making
the enable/disable setting meaningful.

Users can now:
- Disable models in settings they don't want to use
- See only enabled dynamic models in the model selector dropdown
- Have the "Select all" checkbox properly control which models appear

This ensures consistency: enabling/disabling models in settings affects
which models are available for feature execution.
