GriefPrevention Addon - GUI & PvP etc v3.8

Name your listing & search the market
▎ - When listing a claim, a second sign now asks for an optional listing name (leave blank to skip).
▎ - Buyers find claims with /listedclaims <name> or the new /marketclaims alias — matches listing names and seller names, case-insensitive. Tab-complete suggests active listing names.
▎ - Named listings show their name in the Claims for Sale browser, and paging keeps your search filter.
▎
▎ Sign input polish
▎ - Both sign prompts got a clean colour-coded layout: type on the empty top line, hints below (« Sale Price » gold / « Claim Name » aqua).
▎ - Fixed sign text showing blank or colourless in the editor (client sync race) — works across Paper/Folia/Canvas, old and new versions.
▎
▎ Fully customizable: every new text/colour lives in market-messages.yml (sign.price-info-, sign.name-info-, gui.marketclaims.*). New keys are added automatically on restart — no config migration, old market.yml files load fine.

NEW: Teleport to for-sale claims
• Buyers can now teleport to any claim listed on the market before buying it.
• Open Claims For Sale → click a claim → the detail menu now shows Buy, Back and a new Teleport button (left-click to teleport).
• Uses the same safe warmup/countdown system as the own-claim teleport, and respects the teleport.enabled setting.
• Market entry text updated: "Click: preview, buy and teleport".

NEW: Sale lock is now configurable
• market-config.yml → sale.lock-enabled (default: true).
• true = old behavior: a listed claim is fully locked until sold/unlisted.
• false = listing a claim no longer locks it — the owner can keep building, using chests, managing trust, PvP etc. while it's on the market. Purchases stay fully safe either way.

Notes
• New message keys (gui.detail.teleport-name / teleport-lore) and head icon (icons.teleport) are added automatically on restart.
• Existing installs: to get the new market entry text, delete the gui.marketclaims.entry-lore line from market-messages.yml and restart — it will regenerate.
