Checklist

Reviewing is a process done by project maintainers, mostly on a volunteer basis. We try to keep the overhead as small as possible and appreciate if you help us to do so by completing the following items. Feel free to ask in a comment if you have troubles with any of them.

For all pull requests:

• Confirm you have read the contribution guidelines
• You have sent a Contribution Licence Agreement (CLA) as necessary (not required for small changes, e.g., fixing typos in the documentation)
• Make sure the first PR targets the master branch, eventual backports will be managed later. This can be ignored if the PR is fixing an issue that only happens in a specific branch, but not in newer ones.

The following are required only for core and extension modules (they are welcomed, but not required, for contrib modules):

• There is a ticket in https://github.com/GeoNode/geonode/issues describing the issue/improvement/feature (a notable exemption is, changes not visible to end-users)
• The issue connected to the PR must have Labels and Milestone assigned
• PR for bug fixes and small new features are presented as a single commit
• PR title must be in the form "[Fixes #<issue_number>] Title of the PR"
• New unit tests have been added covering the changes, unless there is an explanation on why the tests are not necessary/implemented

Submitting the PR does not require you to check all items, but by the time it gets merged, they should be either satisfied or inapplicable.

Code Review

This pull request performs a large-scale code formatting and import sorting cleanup across various modules of the GeoNode codebase, including base, layers, maps, documents, and harvesting. The review feedback highlights several minor issues resulting from collapsing multi-line implicitly concatenated strings into single lines, which caused missing spaces (such as 'bedeprecated', 'at least{min_digits}', and run-together log messages). Additionally, the reviewer pointed out a spelling typo ('asyncronous') and a duplicate word ('size size') in a document upload form error message along with its corresponding test. All of these comments are highly actionable and include precise code suggestions.

Code Review

This pull request primarily applies extensive code formatting and style updates across the codebase to improve readability and consistency. Feedback on the changes highlights several critical issues: an invalid import path referencing the 'build/' directory in 'geonode/harvesting/harvesters/base.py', a logical bug in test assertions within 'geonode/base/tests.py' where multiple string memberships were incorrectly evaluated using 'and', and a security vulnerability in 'create-envfile.py' where 'random.choice' was used instead of a cryptographically secure random generator for creating the Django 'SECRET_KEY'.
