Added

!Team Auctions

• Team Auctions: team-scoped listings visible and purchasable only by members of the seller's team.
  • New command: /auction team - browse team listings (hidden when disabled or TeamsAPI absent).
  • New command: /auction team sell - list held item as a team auction.
  • team-auctions.enabled toggle in auction.yml (default false).
  • TeamsIntegration facade - null-safe soft-dependency wrapper around TeamsAPI 1.4.0.
  • AuctionListing.teamId field persisted to both YAML and MySQL backends.
  • AuctionListingService team scope and AuctionQueryService team query, both guarded by the config flag.
  • AuctionManager.createTeamListing() and listActiveTeamListings().
  • Team browse tab in the auction browser GUI; tab button hidden when team auctions are disabled or TeamsAPI is not installed.
  • TeamsAPI added to softdepend in plugin.yml.
  • Full message keys added across all four language files (en, es, nl, zh).
  • New permissions: ezauction.auction.team, ezauction.auction.team.sell.

Added (sell menu)

• Price-adjustment buttons replaced with coloured glass panes (lime = increase, red = decrease).
• Second row of quantity-adjustment buttons (same glass style) to select how many of a stack to list.
• SellMenuState.quantity() - tracks the chosen listing amount, clamped to [1, item stack size].
• SellMenuInteractionConfiguration.quantityAdjustments - configurable quantity-step list (default: ±1, ±8, ±16, ±64).
• SellMenuLayoutConfiguration.quantityAdjustmentSlots / quantityDisplay layout fields; inventory expanded from 27 to 36 slots to accommodate the extra row.

Fixed

• Price-adjustment button labels displayed "coins" instead of the configured currency symbol ($ by default). Labels now use formatCurrency() consistently with the rest of the sell menu.
• Chinese (zh) translation files: gui-messages_zh.yml had a duplicate activity preamble block and incorrect 4-space indentation; messages_zh.yml had broadcast and team-auctions merged onto one line and was missing a trailing newline; orders-only.yml had Windows CRLF line endings. All three files now pass YAML validation.
