UI: Add AP cost to enter/exiting tile button

[cat]

While it may seem too obvious to add, having the 1AP cost on enter/exit button is helpful for new players and keeps UI consistency with costs shown on all buttons.

costs are not shown on all buttons, here's a few example of 1 ap costing actions that do not state such

attack
vertical movement (in/out)
horizontal movement (standard)
search (okay admittedly these two
hide are mostly my doing to cut down on ui bloat)
cast spell
trigger spellgem

For the ones listed which are generally static like tile movement I would say add those too.
I'd love to see movement buttons reflect actual AP costs with moveskills if it's doable.
Spells, charged attacks etc are trickier as you'd want to list all other costs too, I would wait until those can be included in a more extensive UI/UX overhaul.

if i could colour or otherwise differentiate buttons for 0 ap actions and others i would but html input design is very limited
