- Create `Base` and inherit `Sheet` and `Expanded` in order to
- prevent code duplication.
  - Remove trailing "\n" for components of `Expanded`.
  - There is no need for `Expanded#header` to return `@buffer` so return `nil` instead.

- Change `no_routes` message "No routes were found for this controller"
  since if use `-g`, it sounds incorrect.
  - Display `No routes were found for this controller.` if apply `-c`.
  - Display `No routes were found for this grep pattern.` if apply `-g`.

Related to #32130

- Add a mention about `-g`.
- Improve info about `--expanded` option of `rails routes`.

Since `Redis#call` duck types as a Proc, we'd call `#call` on it,
thinking it's a Proc. Fixed by check for the Proc explicitly instead of
duck typing on `#call`.

Perform enqueued delivery jobs in #assert_emails and #assert_no_emails.

The Active Storage service for Azure Storage has an option called `path`
that is ambiguous in meaning. It needs to be set to the primary blob
storage endpoint but that can be determined from the blobs client anyway.

To simplify the configuration this commit removes the `path` option and
gets the endpoint from the blobs client instead.

Closes #32225.

Closes #32219.

Draw line of a route name to the end of row console on `rails routes --expanded`

Since Rails 6 requires Ruby 2.4.1+.

Currently, `Exiting` is showed during server startup.

```
./bin/rails s
=> Booting Puma
=> Rails 6.0.0.alpha application starting in development
=> Run `rails server --help` for more startup options
Exiting
Puma starting in single mode...
* Version 3.11.2 (ruby 2.5.0-p0), codename: Love Song
```

This is because processing at server stop is passed as a block, and
`Rack::Serve#start` receives a block and executes it during startup processing.
https://github.com/rack/rack/blob/50db1ffdf8b98503fb7c6e6648622b5d7d78d58e/lib/rack/server.rb#L258

In order to avoid this, stop processing is passed as argument.

Only apply URI.unescape monkey-patch if detected to be required

We test the failing case we're trying to patch; only if it throws an
Exception do we patch.

Currently this will *always* throw, but upstream Ruby has patched this
bug: https://git.io/vAxKBSigned-off-by: NAshe Connor <ashe@kivikakk.ee>

If the app has the CSP disabled globally allow a controller action
to enable the policy for that request.

e.g:

    class LegacyPagesController < ApplicationController
      content_security_policy false, only: :index
    end

We use inline style and script for the view held inside Rails like
welcome page and mailer preview.
Therefore, if inline is prohibited by CSP, they will not work properly.
I think that this is not as expected. 　

For that reason, I have made it possible to use inline style and script
regardless of application settings.
