Simplify user_image and user_thumbnail css

Now that all uses of the images and thumbnails have been migrated
to flex grids, we can remove the margin and padding from the original
css classes and revert to using them.

Use grid for dashboard map popups

Use flex grid for issue reports and comments

Use flex grid for diary index headings

Rework diary entries to use grid when a heading thumbnail is shown

This happens on the index page, but not individual show pages. I've
reversed the if condition to avoid having an else on a negative
condition.

Use grid for diary entry heading layout

This brings it into line with the user profile, which has a similar heading

Rework diary comments to use flex grid rather than floats and margins

Remove custom css overrides for the users list

The margins on the buttons aren't needed since the table has a bottom
margin, and the button class has never been applied since it was
incorrectly in the id field. The table row override had no effect since
the cells have their own vertical-alignment set.

Remove the paragraph margin overrides for the users list

Add button classes for users list action buttons

Remove the contact-activity class

The margin-top is better replaced with a bottom margin on the
preceding element, and the width is unnecessary in the grid layout.

Remove custom margins on sidebar headings

Margin-top in particular is best avoided. The removal of some top
margins required a few corresponding changes to add bottom margins
to other features, mostly done by converting bare text strings to
live within paragraphs.

Use flexbox instead of floating to position the comment icon

Specify avatar dimensions in html tags

This prevents reflow when the images are loaded by the browser.

ActiveStorage variants are resized lazily when the image is requested,
so we only know the dimensions if the image was already loaded. This
means that there will be one reflow just after a new avatar is first
viewed.

Move the tracepoint coordinate format test to the controller test

Refactor tracepoint index to use an xml builder view

This avoids constructing xml by hand in both the controller and
the model, and opens the way for other rendering in future.

The complexity of deciding which point goes where, along with revisiting
previous tracks and tracksegs means that I've broken it down into
two parts - sorting the points into the right trksegs is done first,
before rendering them all as xml. I couldn't find a way to allow
revisiting using the builder.
