fix: rename PluginContext to AppPluginContext to avoid duplicate identifier with @objectstack/spec

The @objectstack/spec package already exports a PluginContext type that is
re-exported from @object-ui/types. Renamed the ObjectUI-specific plugin
context interface to AppPluginContext to avoid TS2300 duplicate identifier.
