feat: add nickname history feature (History button, searchable popup, Paste/Copy/Delete, XML persistence)

[DateFTP]

Summary

This PR adds a Nickname History feature to the MTA client Settings window (Multiplayer tab). When a player changes their nickname, the previous nickname is automatically saved to mta/logs/nicknames.xml. The player can later browse, search, paste, copy, or delete entries from the history popup.

---

Changes

Client/core/CSettings.h

• Added member variables for the Nickname History UI: button, popup window, grid, search field, action buttons
• Added column handles (m_hNickHistoryColNick, m_hNickHistoryColDate)
• Added cache (m_NickHistoryCache) for nickname entries
• Added cached file path (m_strNicknamesFilePath)
• Added friend callback declarations for the Delete/DeleteAll question box
• Added method declarations: SaveNicknameToFile(), RewriteNickHistoryFileFromCache()

Client/core/CSettings.cpp

GUI creation (CreateGUI):

• Added History button (60x26) to the right of the random-nick generator button
• Created a popup window (600x460) titled "Nickname history" with:
  • Search field (filters by nickname or date in real-time)
  • Grid list with two columns: Nickname (65%) and Date (35%)
  • Paste to nick - copies selected nickname to the edit box
  • Copy - copies selected nickname to clipboard
  • Delete - removes selected entry (with confirmation)
  • Delete All - clears entire history (with confirmation)
  • Close - closes the popup

XML persistence:

• SaveNicknameToFile() - loads existing entries from
  icknames.xml into the cache, appends the new nickname with a timestamp, then rewrites the file from the cache. This ensures old entries are never lost.
• RewriteNickHistoryFileFromCache() - writes the entire cache back to XML. Uses MakeSureDirExists() before writing, so the file and/or logs/ directory are re-created automatically if deleted.
• Constructor pre-creates
  icknames.xml with an empty root if the file is missing.

Question boxes:

• "DELETE NICKNAME" confirmation with "Delete nickname "%s" from history?" message
• "DELETE ALL" confirmation with "Delete all nicknames from history?" message

All UI strings are wrapped with _() for gettext localization.

Locale files (43 languages)

Added the following new translation entries to client.pot in every locale directory:

• "History", "Nickname history", "Nickname", "Date"
• "Paste to nick", "Copy", "Delete", "Delete All"
• "DELETE NICKNAME", "Delete nickname "%s" from history?"
• "DELETE ALL", "Delete all nicknames from history?"

How it works

1. When the user clicks OK in the Settings window, if the nickname has changed, the previous nickname is written to mta/logs/nicknames.xml with a timestamp.
2. The History button opens a popup showing all previously saved nicknames in a searchable grid.
3. Paste to nick replaces the current edit-box nickname with the selected history entry.
4. Copy copies the selected nickname to the system clipboard.
5. Delete and Delete All show confirmation dialogs before removing entries.
6. The XML file is rebuilt entirely from the in-memory cache on every modification, keeping it consistent and preventing data loss.
7. If
   icknames.xml or the logs/ directory is deleted at runtime, the code recreates them automatically.

I don't see the purpose of having a nickname history. This seems rather useless? In what realistic scenario would a user require this?

Also, please advise your LLM that translation files aren't created manually.

@Lpsd Some players will find the nickname history feature useful. As a player, I find this feature interesting. For example, if I change my nickname and forget my old nickname, I can go to the nickname history and retrieve my previous nickname.

@Lpsd I'll check if my language model has made any mistakes in the language and locale. I understand that this is not the correct way to load languages.
