non-functional: sync Decks with libAnki

[david-allison]

Purpose / Description

Decks was pretty badly out of sync with decks.py

https://github.com/ankitects/anki/blob/main/pylib/anki/decks.py

I want to get back in sync, as #15611 has shown that we still have issues.

• [BUG]: All card options show (end) #15611 (comment)

This will also allow us to more easily deprecate the legacy methods, rather than using a combination of new and legacy methods

DeckManager.register_deprecated_aliases(
    confForDid=DeckManager.config_dict_for_deck_id,
    setConf=DeckManager.set_config_id_for_deck_dict,
    allConf=DeckManager.all_config,
    getConf=DeckManager.get_config,
    confId=DeckManager.add_config_returning_id,
    newDyn=DeckManager.new_filtered,
    isDyn=DeckManager.is_filtered,
)

As a long-term stretch goal, this brings us closer to automation to map from libanki to pylib

Approach

• rename + reorder methods
• Introduce LibAnkiAlias: I suspect we'll eventually want all methods in libAnki to be annotated by this OR NotinLibAnki. This makes it easier to map from libanki to pylib
• Brief look through and add cleanup annotations where necessary

How Has This Been Tested?

Ran unit tests, then rebased onto main
