V246 - LIVE ACCOUNT-BOUND SLOT / LOCK AFTER LEAVE OR KICK

- Based on the supplied V244 build.
- A multiplayer Character Slot is account-bound only while a connected player fills/owns that slot.
- Only that account/player can select or edit its bound slot.
- If the player leaves, Arbitration opens as before; the live character is removed there.
- If the player is kicked, the live character is removed immediately on Arbitration.
- After leave/kick, the account binding is fully released.
- The empty released slot is locked/unselectable.
- The slot becomes selectable/account-bound again only when another connected player is assigned to/fills that slot.
- Pressing Play continues normal gameplay and does not itself force Arbitration.
- Account CHR/BIO files are untouched. No character backups or automatic restoration are added.
