* Improve ActiveStorage asset linking performance

Use direct links to the assets living at storage services in order
to push most of the application load to the storage service
instead of the website itself.

* Fix issues serving image variants directly through the storage service

The image variants need to be processed through the local
representation URLs when they are served the first time because
this is when these assets are processed for the first time.

These changes detect if the variant needs processing and serves
it through the local representation URL before the image has been
processed. If the image is already processed it is served directly
through the storage service itself.

* Fix and extend the storage asset router specs

- Fix the storage asset specs to match the current implementation
- Add more tests to test the router under different configurations
  and options
- Add an RSpec support utility to define the storage host when the
  storage URLs are tested outside of a request context

* Fix typo

* Define the current host for the assets for all specs

In order to avoid adding the asset support hooks to too many
specs.

* Fix spelling issues

* Improve the storage router logic for local disk storage

- Add more logic for the disk service to determine the
  availability of the current host before generating the URL
- Define the current host based on the record if the record has
  details about its organization, only if the current host hasn't
  been set already

* Add the ActiveStorage::SetCurrent concern to devise controllers

* Fix specs broken due to the changes in the asset URL generation

As the URLs are now changed every time they are generated, this
caused some specs to fail that assumed the URL of the asset is
matches always the format in which it was first generated.

The asset URL includes the expiry information and the expiry
information is different every time the URL is requested.

* Fix spelling in variable name

* Different strategy to escape the string included in the regexp

* Fix id documents verification flaky spec

* Fix further specs expecting blob URLs

As the URLs can be different every time they are requested, use
different strategy for testing.

* Use different matching strategy for questionnaire file answers

In order to fix the CodeQL violations.

* Fix flaky specs for inviting process users

* Fix assembly serializer spec for checking the file URLs

* Consider that the asset can be  in the generators spec

* Fix participatory process group type spec for checking the file URLs

* Test the participatory process presenter without setting the current host

* Ensure that  also exists at the storage service

In case the variant is already created at the database but not
yet uploaded to the storage service, it might not be available
yet.

* Method naming and add documentation to the new method

- Use the same conventions for the method name as Ruby and Rails
- Add method documentation

* Add a note about checking that the variant exists at the storage

* Add a spec for unexisting and processed variant with record

Test the situation when ActiveStorage reports the asset to be
processed but it does not exist at the storage service as this
caused some of the system specs to fail before.

* Use the  matcher instead of

* Improve the regexp matching in the asset router

* Fix passing incompatible URL options to

* Simplify logic

The options do not need to be merged twice.

* Apply suggestions from code review
