Fix: display actual Alliance extension message instead of translation key (#1532)

## Description:

On Alliance extension, the key "events_display.alliance_renewed" is
displayed in the Event Panel. Reported in
https://discord.com/channels/1284581928254701718/1397197460085932184

Since displayMessage doesn't expect or do translations, just puts out
hardcoded English messages so far, it doesn't do anything with the
recieved key and just puts it in the Event Panel as is. This PR fixes it
as a follow-up of #1359.

With this, it also introduces a base which can be used to translate
hardcoded messages coming from other Executions. That is out of the
scope of this PR.

PRs #1532 and #1536 both fix issues with Alliance Renewal in v24. If
possible approve 1532 (this one) first and then 1536 not too far after
if github can indeed merge them.

AFTER: 
(tested locally with Nations by not checking their answer; they normally
don't answer to alliance renewal request which is another issue)
