What changes are proposed in this pull request?

Prepares the documentation and a few broken code paths for the 4.12 release. Four commits:

1. [docs] Refresh the user, admin and developer docs for 4.12
   • Align the installation, configuration, API and developer guides with the current code: Python 3.11, Django 5.2, Gunicorn as the default server, the new Importer and Storage Browser.
   • Rewrite the REST file browsing and importer API docs from the real routes and parameters.
   • Remove the outdated Cloudera Manager, CDH, Python 2, gethue CLI and dead JIRA content.
   • Fix the broken anchors and code blocks, and update the release checklist.
2. [core] Fix management commands with positional arguments on Django 5.2
   • close_queries, close_sessions, beeswax_install_examples, hbase_setup and create_proxy_app read their arguments from args without declaring them, so Django 5.2 rejected them. Declare the arguments and add tests.
   • handle() callers in the code are not affected.
3. [helm] Remove the disabled hue-api chart pieces and the Compose doc
   • The gethue/compose image no longer exists. Remove the hue-api deployment, service, values and ingress entries (all disabled by default) and the Compose design doc.
4. [core] Align hue.ini and the ini template with the code defaults
   • Fix defaults and comments that disagree with the Config definitions, remove keys that no longer exist and add the missing user-facing options.

How was this patch tested?

• The new tests pass (24 tests in the management commands and beeswax management tests). ruff is clean on all changed Python files.
• The docs site builds with Hugo and has 0 broken internal links. A scan found no raw markdown on any page.
• Four independent fact-checks of the docs against the code. The confirmed errors were fixed.
• hue.ini loads in Hue's config loader.
• Not run: helm lint and helm template, because helm is not installed here. The commands were not run against a live Hive or HBase.

Note: to preview the docs locally, use Hugo 0.62.0 (the version of the docs image). Hugo 0.69.0 collapses the left menu for some pages.
