block search and block page improvements

[LuizAsFight]

problems here:

• when searching for height, it shows both height and hash occurrence. Should show only the one that was searched to don't generate confusion
• in the searchbar it only works if you click over the text. should work if you click in any part of the item result
• subtitle of page is showing what comes from URL, it should show always the hash
• add a new card with Block Height
  • one detail is check if it will look good in mobile
• horizontal scroll in search block should not existe
• the size of "search results" should be the same of the input
