* Add respawn action for ghosts with confirmation popup
Introduces a new respawn action for ghosts, allowing them to return to the lobby and respawn as a new character. Adds supporting systems, localization, prototype definitions, and an icon for the action. The action includes a confirmation popup to prevent accidental use.
* Prevent respawning with the same character in a round
Introduces a system to block players from rejoining a round with a character that has already died, notifying them with a localized message. Refactors and moves respawn-related localization strings to new files for both English and Russian.
* Prevent admins from character reuse restriction
Added a check in CP14RespawnSystem to allow admins to bypass the restriction that prevents the same character from re-entering the round. This ensures that admin users are not limited by the character reuse logic.
