Contracts & Bounties 0.4.1 — Visual material selection

• Replaced the raw item-ID field with a visual catalogue of registered Vanilla and modded items, using real icons and localized names.
• Added accent-insensitive name search, optional namespace/ID/#tag filters, pagination, keyboard selection and a main-inventory filter that excludes customized items.
• Preserve the title, quantity and reward while selecting or cancelling, resizing and receiving server policy refreshes. An expired session closes the catalogue; revoked publication permission returns to the board.
• Refreshed the board and form with emerald lacquer, gold trim, parchment cards, material icons and clearer selected tabs.
• Kept the existing single-item contract target, server validation, protocol 3, escrow, taxes, rewards and saved-data formats.
• Added search and viewport regression tests plus actual Minecraft catalogue, draft, selection and compact-screen checks in English and Portuguese.
