Inject default codes into ResourceSettingsModel

[edan-bainglass]

Based on #1363

This feature was unintentionally removed in the MVC redesign. Restored here.

Major update

Implementing this PR revealed several other issues, which are also addressed here:

• Resource models have code models. These code models were only partially subscribed to events, with remaining subscriptions only applied at render time. This is not an ideal MVC implementation. It is now corrected here by way of ResourceSettingsPanel.register_code(code_model: CodeModel), which is injected into the logic of building the global codes (GlobalResourceSettingsPanel.build_global_codes, formerly set_up_codes.
• The generate_qeapp_workchain test fixture was using deepcopy on inputs. This results in duplication of AiiDA nodes, which in turn led to a raised MultipleObjectError on subsequent use of the fixture due to code duplication of identical labels. See Use shallow copy to avoid creating a new AiiDA node every time #1341 for more details.
• test_create_builder_default regression data is corrected here to reflect num_cpus = 2, which was not captured before
• We were using an old AiiDA testing fixture for generating codes. This is also updated here.
• Also noticed during testing several deprecations warnings from ipywidegets/traitlets (e.g., traitlets.List(trait=taitlets.Int) instead of traitlets.List(trait=taitlets.Int()), passing unrecognized arguments to constructors, etc.). Fixed here.

Peripheral changes

• Consolidate some imports at top of modules for quick reference. Should not affect app loading time, as these do not execute code (I believe, and truly hope they don't. Otherwise, we should adjust them).

I just check and the codes are uploading fine ,but i realize the functional (I went to step two) was selecting the default (PBESol) instead of the one I used (PBE)

Interesting. I'll have a look in the morning.

Update

@AndresOrtegaGuerrero Fixed in #1373. I missed setting it in the family-string branch of the if-block. Have a look/test 🙏
