Don't tint editor bottom panel icons when hovered or pressed

This prevents the error/warning icons from turning gray or green,
making them hard to recognize. A similar mechanism is already used
for EditorLog filter button icons.

This also fixes typos in FileDialog theme color assignment
(`icon_color_pressed` instead of `icon_pressed_color`). The exposed theme
item names remain the same.
