More GUI improvements

Related issue (if applicable): refs n/a

This pull request focuses on developer and operator usability improvements in
Apprise-API, with a particular emphasis on:

• Improved instructional text and layout in the configuration template.
• Minor template clean-up and formatting alignment for the help content.
• Updated the configuration list view to support API based calls so it can return JSON when requested,
  instead of always rendering the template.
  • This enables programmatic consumption of configuration IDs/keys.
• The API version is now exposed in headers in addition to the Apprise library
  version, reducing confusion about the relationship between the two packages.
• /cfg/<key> now accepts POST in addition to the previous retrieval approach acting exactly how /get/<key> POST works. /get/ would return the users configuration when it was posted to. It makes sense to use /cfg/<key> as well for users who copy/paste URL's from their Apprise API instance directly (from the browser URL). Basically /cfg/<key> is now an alias of /get/<key>
  • /get/<key> remains supported for backwards compatibility. No plans on removing this either.
• Expanded swagger.yaml substantially to better document the service.

  • Added a dedicated docker-compose.swagger.yml to launch Swagger UI pointing
    at the repository swagger.yaml without altering Apprise-API runtime.

    docker compose -f docker-compose.swagger.yml up -d
    # Browse:
    #   http://localhost:8001

• improvements to README.md
• heath checks are now live when viewing the website
• heavy changes to workflow:
  • development environment is now just tox -e runserver
  • improvements to linting and formatting

In short, this is a huge refactor of the existing setup 🔥 🚀

Pull request overview

This PR enhances the Apprise API GUI with improved user experience features and API consistency. It adds the ability to copy the Config ID to clipboard, allows retrieving configuration via POST to /cfg/<key> (in addition to /get/<key>), and displays both the Apprise API and Apprise Library versions in the header to reduce confusion between the two packages.

Key changes:

• Added Config ID copy-to-clipboard button functionality in the GUI
• Extended /cfg/<key> endpoint to accept POST requests for configuration retrieval (mirrors /get/<key>)
• Updated header to display both Apprise API version and Apprise Library version
• Extensive CSS formatting improvements for consistency across theme files
