Fix external issue tracker "Issues" link leading to 404s

## What does this MR do?

This MR fixes the redirection to the wrong URL when using an external issue tracker, such as JIRA or Redmine.  a70431f8 modified the behavior to link to the external issue tracker
issues URL instead of the project path URL. This restores the previous behavior.

## Why was this MR needed?

The issues URL often has `:id` associated with it for linking mentioned issues.
For external issue trackers, the project page is the intended target.

## What are the relevant issue numbers?

Closes #21252

Related to #21402

Remove max height on pipelines graph

#### What does this MR do?
Removes max-height from pipeline graph

#### Why was this MR needed?
The height was originally put in place because some stages have ~20 tests, which ends up looking a little lopsided and there's a large amount of white space. The scrolling container, however, is not the best solution and ends up being more difficult to scroll around to find what you're looking for. For now we can remove the height, and eventually we'll have the similar tests collapsed.

Fix unnecessary horizontal scroll area in pipeline visualizations

## What does this MR do?

Removes a min-width attribute for the build pipeline visualization wrapper

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

I am curious why this line was there in the first place.  Perhaps I'm just not seeing it.

## Why was this MR needed?

I was noticing an unnecessary horizontal scroll bar when viewing pipeline visualizations embedded in merge request builds tab:

Handle non-UTF-8 conflicts gracefully

## What does this MR do?

See merge request !5961

If the received id is still a pending todo mark it as done

## What does this MR do?

Just return properly on stale todos, for me is annoying to mark as done a todo that is already done and the done hung there forever, so I have to refresh the page. I decided to resolve the issue myself.

## What are the relevant issue numbers?

Closes #19730

Handle unavailable system info

## What does this MR do?

Handle the case where we can't get system info without blowing up. As this is the first tab in the monitoring section, it's difficult to get to the other tabs if this page throws a 500. Also be more specific about the info we want, so we don't fail on something we don't care about (like `/proc/net/dev`).

## Why was this MR needed?

grsecurity can prevent users from reading `/proc`, which is what Vmstat uses to find CPU and memory info.

## What are the relevant issue numbers?

Closes #21378.

Ensure all javascripts use GitLab install directory as the cookie path.

## What does this MR do?

Fixes #20435 and standardizes all JavaScript-set cookies to use the same root url.

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

Nothing I can think of.  This MR is pretty straight forward.

## Why was this MR needed?

Cookie paths were inconsistent across front-end scripts.  Some would default to '/' and others had no set path and would end up tied to whatever page they were set on.  Also as @connorshea noted, we cannot assume GitLab is installed at '/'.

Automatically expand hidden discussions when accessed via a permalink hash (closes #19304)

## What does this MR do?

Addresses "Auto-expand a discussion note when we arrive via anchor" (issue #19304)

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

Let me know if the code is consistent with community standards (not 100% sure about indentation of chained jQuery actions)

I don't think this MR warrants any unit tests or documentation, but let me know if you disagree.  I'll add the requisite CHANGELOG entry upon approval.

## Why was this MR needed?

Currently, if a discussion is accessed via a permalink to an "outdated" diff discussion, the anchor will not bring you to the expected part of the page.
