performance: Refactor how data is managed to reduce copying.
* Make use of `collections.abc.Mapping` to better identify things that are
supposed to look like dictionaries.
* Instead of handling "overlay" of data in a dict tree in each different data
object, make all objects `Mapping`s and handle merging at a higher level
with the new `MergedMapping` object.
* Since this new object is read-only, remove the need for deep-copying of
app and page configurations.
* Split data classes into separate modules.
