MPT-16437 Reorganise resource catalog mixins structure

[albertsola]

Closes MPT-16437

• Reorganise catalog mixins into separate modules for clearer structure and maintainability.
• Add ActivatableMixin and AsyncActivatableMixin (mpt_api_client.resources.catalog.mixins.activatable_mixin) with activate() and deactivate() helpers.
• Add DocumentMixin and AsyncDocumentMixin (mpt_api_client.resources.catalog.mixins.document_mixin) composing create-file, download-file and publishable capabilities.
• Add MediaMixin and AsyncMediaMixin (mpt_api_client.resources.catalog.mixins.media_mixin) composing create-file, download-file and publishable capabilities.
• Refactor publishable_mixin.py to retain only PublishableMixin/AsyncPublishableMixin (removed composite mixin definitions).
• Centralise public exports in mpt_api_client.resources.catalog.mixins.init.py to re-export all mixins.
• Add focused unit tests for Activatable, Document and Publishable mixins (sync + async) in dedicated test modules.
• Remove legacy tests/unit/resources/catalog/test_mixins.py (tests migrated to module-specific files).
• Remove several per-file lint suppressions from pyproject.toml related to the reorganised files.

📝 Walkthrough

Walkthrough

Splits composite catalog mixins into separate modules (activatable, document, media), re-exports all mixins from mpt_api_client.resources.catalog.mixins.__init__, removes duplicate composite classes from publishable_mixin.py, updates pyproject lint ignores, and moves tests from a consolidated module into focused mixin test modules.

Changes

Cohort / File(s)	Summary
Re-exports mpt_api_client/resources/catalog/mixins/__init__.py	Adds explicit imports and updates __all__ to re-export Activatable, Document, Media, and Publishable mixins and their async variants.
Activatable mixin mpt_api_client/resources/catalog/mixins/activatable_mixin.py	Introduces ActivatableMixin and AsyncActivatableMixin with activate() / deactivate() delegating to _resource_action.
Document composition mpt_api_client/resources/catalog/mixins/document_mixin.py	Adds DocumentMixin and AsyncDocumentMixin composing CreateFile/DownloadFile/Publishable mixins (sync and async variants).
Media composition mpt_api_client/resources/catalog/mixins/media_mixin.py	Adds MediaMixin and AsyncMediaMixin composing CreateFile/DownloadFile/Publishable mixins (sync and async variants).
Publishable cleanup mpt_api_client/resources/catalog/mixins/publishable_mixin.py	Removes previously in-file composite mixin classes and unused imports; retains PublishableMixin (and async variant) implementation.
Lint config pyproject.toml	Removes several per-file WPS lint suppression entries related to mixins and seed files.
New focused tests tests/unit/resources/catalog/mixins/test_activatable_mixin.py, tests/unit/resources/catalog/mixins/test_document_mixin.py, tests/unit/resources/catalog/mixins/test_publishable_mixin.py	Adds unit tests for Activatable, Document, and Publishable mixins (sync and async), validating HTTP request formation, multipart handling, and response mapping.
Removed consolidated tests tests/unit/resources/catalog/test_mixins.py	Deletes the previously consolidated mixins test module; tests redistributed into the new focused test modules.

In `@tests/unit/resources/catalog/mixins/test_publishable_mixin.py`:
- Around line 73-102: Remove the unused input_status parameter from the
parametrization and the test signature in test_custom_resource_actions_no_data:
update the `@pytest.mark.parametrize` tuple to only include ("action",) and change
the function definition to def
test_custom_resource_actions_no_data(publishable_service, action): so the unused
input_status is not passed into the test; apply the same edit to the other
analogous no-data test in this module that was similarly parametrized (the other
test covering the publish/review/unpublish actions).
