Bank Clerk NPC added with a dedicated Lithera Bank menu for group accounts and safe deposit boxes.

Group bank accounts: create named shared accounts, invite online players, manage members, rename accounts, leave accounts and delete empty accounts.

ATMs now support personal and group account selection for deposits, withdrawals and transaction history.

Group account rules are configurable, including max members, max led accounts, name length, withdrawal policy and transaction history size.

Safe Deposit Box: permanent bank storage that survives death and reconnects, with item drag/drop between backpack and safe slots.

Safe deposit slots can be upgraded from the bank menu using bank funds, with configurable slot totals, default unlocks, access window and purchase tiers.

Bank menu opens the backpack while using the safe deposit tab and blocks accidental ground drops during safe storage operations.

Default bank clerk placement and NPC config support added in configs/npcs.json.

Admin Economy panel can audit group bank accounts, set shared balances and delete group accounts with dedicated permissions.

Admin Inventory panel can view safe deposit boxes, set unlocked safe slots and clear safe deposit contents with dedicated permissions.
