Suppress AJAX errors... again

Closes #32716

See merge request gitlab-org/gitlab!17706

Resolve "Discussion counter is wrong on issue page"

See merge request gitlab-org/gitlab!16567

Resolves the situation where the Discussion tab counter
would sometimes reflect the wrong count. We were relying
on the list of `allDiscussions` but it's more complicated
than that. We have to filter out system notes and count
all individual notes in threads.

Plus, we already have a getter for that.

Remove nested Promise from user popover

See merge request gitlab-org/gitlab!17688

This commit attempts to detect when errors are caused due to AJAX
requests being cancelled when the user navigates to a new page. If this
is the case, we swallow the error so that an error message isn't shown
to the user a split second before they navigate away from the page.

Refactor Security Dashboard store

See merge request gitlab-org/gitlab!17250

This refactoring is part of the [Instance Security Dashboard MVC][1], to
abstract away from the base Security Dashboard the logic for how the
list of projects to filter with is set. It:

* Adds a new `GroupSecurityDashboard` component that wraps the
  `SecurityDashboard` component.
* Moves the `projects` module bindings/calls from the
  `SecurityDashboard` component to the new `GroupSecurityDashboard`.
* Creates a new `projects` plugin for the Security Dashboard store which
  dynamically adds the `projects` module and sets up the appropriate
  store bindings between it and the `filters` module.
* Updates the entry point for the Group Security Dashboard to add the
  `projects` plugin to the Security Dashboard store.
* Moves the existing `mediator` and `sync_with_store` plugins into
  a `plugins` directory.
* Renames `moderator` to `mediator`.
