[Bug] Nicknames not properly sanitized (#5537)

* Fix #5082: Nicknames not properly sanitized
When a player changes the name of the pokemon
to one that uses one of the following combination
of letters: "@c{}", "@s{}", "@d{}", "@f{}" and "$"
the game shows the name of the pokemon incorrectly in a battle.
Changes made:
- on message-ui-handler.ts file I updated the "showTextInternal"
function to get the original name of the pokemon
or pokemons (in case it's a double battle) saving it in a list
named "pokename" and change it in the text for their
correspondent placeholder which is saved in the list "repname"
(e.g "#POKEMON1" for the first pokemon and "#POKEMON2" for the
second pokemon). After the text is properly modified because
of the special characters ("@c{}", "@s{}", "@d{}", "@f{}")
the name of the pokemons is replaced to it's original value.
- on message-phase.ts file I updated the "start" function to use a
similar approach but only change the pokemon name to it's original
form after the "pageIndex" (which checks the index of the "$")
is updated, so the text is cut properly.
- on ui.ts file I updated the "showtext" function to use same
approach of the previous files, ensuring that the pokemon names
were only replaced back to their original values after all text
processing on "$" was completed.

* Replace `let` with `const`
