Fix bug where e-mails were not being sent out via Sidekiq

By default, ActionMailer uses the "mailers" queue, but this entry
was not included in the list of queues for Sidekiq to use.

Use separate queues for all Sidekiq workers

## What does this MR do?

This MR updates all workers so that they (mostly) use their own Sidekiq queues. This in turn allows us to monitor queues more accurately and in the future impose queue specific throttles, limits, etc.

This is a critical part we need in 8.13, despite it being so close to release day.

See https://gitlab.com/gitlab-org/gitlab-ce/issues/23370 for more information.

Disable warming of the asset cache in Spinach tests under CI

I suspect some combination of Knapsack tests cause no regular Rack tests
to be loaded (i.e. all JavaScript tests), which leads to the error:

ArgumentError: rack-test requires a rack application, but none was given

In CI, we precompile all the assets so there is no need to warm the
asset cache in any case.

Closes #23613

Fix broken label uniqueness label migration

The previous implementation of the migration failed on staging because
the migration was attempted to remove labels from projects that did not
actually have duplicates. This occurred because the SQL query did not
account for the project ID when selecting the labels.

To replicate the problem:

1. Disable the uniqueness validation in app/models/label.rb.
2. Create a duplicate label "bug" in project A.
3. Create the same label in project B with label "bug".

The migration will attempt to remove the label in B even if there are no duplicates.

To fix the issue, include the project ID when selecting the labels.

Closes #23609

Fix GitLab project import when a user has access only to their default namespace

## What does this MR do?

It fixes a bug when a namespace ID was not passed to `/import/gitlab_project/new` page. It occurred when a user have no choice of the namespace, so we did not render the input for namespace ID. This MR introduces a hidden input for the described case.

Fixed issues with sticky mr tabs & sidebar

## What does this MR do?

- Fixes an issue where opening the sidebar wouldn't update the merge request tabs width & positioning
- Fixes issues when resizing the browser

Rather than updating the JS to react to different methods, this way allows the CSS to keep control of the positioning & sizes.

[Doc] Fix `ref` parameter name for `commits/statuses`

The attribute to filter by branch or tag needs to be named `ref`, not `ref_name`. And indeed the attribute in the JSON response is `ref` (and not `ref_name`).

Restrict ProjectCacheWorker jobs to one per 15 min

## What does this MR do?

This restricts performing ProjectCacheWorker jobs to once every 15 minutes per project. The goal of this is to reduce disk load in the event of a lot of pushes happening in a short period of time. 

The impact is that cached data (e.g. commit count) may be updated less frequently. Furthermore it could mean that separate push payloads won't lead to e.g. READMEs being updated. Most of the cached data isn't updated very frequently, so this trade off should be worth it considering the alternative is a burning storage layer. 

In the future we'll have to flush caches in a smarter way. For example, refreshing the README cache could probably be done separately from the other caches with its own lease and such. See https://gitlab.com/gitlab-org/gitlab-ce/issues/23550 for more information.

Fix a 500 error viewing an MR with a deleted source project

## What does this MR do?

Allows merged MRs to be shown without any 500 errors if the source project is removed

## Are there points in the code the reviewer needs to double check?

https://gitlab.com/gitlab-org/gitlab-ce/commit/31c37c6c38258684fc92e0d91119c33872e39034 fixed this for closed MRs only. I had trouble understanding the introduced helper and logic, so reverted it and keyed everything on the existence of the source project or branch directly.

commits.json returns a 500 error for a closed or merged MR; the approach taken in the above MR was to hide the commits... tab, so I've run with that.

For merged MRs, the commits (but not the pipeline data) are in the target project, so we *could* do better, but it's a fairly nasty intervention to make it happen.

## Why was this MR needed?

Viewing merged MRs should work even if the fork they came from has been deleted or unlinked.

## Screenshots (if relevant)
