[BUGFIX] Align pagination in recycler and workspaces

EXT:recycler and EXT:workspaces use nearly the same
code for their custom JavaScript based pagination.

Therefore, both are adjusted accordingly.

All buttons are now always equal height, since
the "page-link" class now uses the full parent
container space.

The prev / next buttons now use the TYPO3 icon
element instead of font awesome, making additional
classes superfluous.

All buttons are now "buttons", since they do not
contain a target. This also brings previously
missing user agent styles, such as cursor:pointer.
Also the full area is now clickable.

Additionally, a left over code block from #81086
is removed in the Recycler JavaScript module.

Resolves: #95251
