AuctionOverlay

### ★ New in 1.7.1: Live show
Everything that makes an auction more exciting on stream, in one place (★ in the live menu and setup, `/bidding show`):
- **Overtime on late bids** (optional: off · 10 · 15 · 20 · 30 s): if someone takes the lead in the last seconds, the countdown jumps back up – "OVERTIME · 15 s left" in the HUD, live menu and OBS. The hard stop at 00:00 stays the default.
- **Countdown show:** "GOING ONCE! · GOING TWICE! · LAST CALL!" with a bell at 10, 5 and 2 seconds (as soon as there is a top bid).
- **Auction playlist:** all prepared slots run one after another (setup → *▶▶ Playlist* or `/bidding playlist start`) with an adjustable break in between (default 1:30). HUD and OBS show "Next auction in 0:45" with the item. Pause, skip or stop at any time. The mod never writes to the chat.
- **Stream summary** (`/bidding summary`): revenue, auctions, bids, bidders, biggest sale, top supporters and every sale of the session. *Show on stream* shows it in the OBS overlay for 30 s, *Copy* puts it on the clipboard (e.g. for Discord).

### ⚡ Faster & nicer
- **Much smoother:** the open live menu now costs 0.9 instead of 7.9 ms per frame (test machine: ≈ 100 → 320 FPS). HUD, setup and settings are 3–7× faster.
- **Nicer:** smooth circles and medals, soft gradients, a light spot on the podium, a shadow under the HUD (easy to read even in front of bright worlds).
- **OBS overlay without delay:** every bid shows up the moment it arrives (before: every 250 ms). Older browser sources keep polling automatically (`…/overlay?poll=1` forces that).

### Also new 
- **Restore after a crash or disconnect:** when you rejoin, the mod asks *Resume*, *Evaluate now* or *Discard* (`/bidding restore`).
- **Cents** like `$0.99` or `$1,234.56` are detected and added up exactly.
- **Add a bid by hand** (`/bidding add`, *+ Bid*) and **remove bidders** (right-click twice, `/bidding remove`) – for unrecognized payments or trolls.
- **Learn a server's payment format** (`/bidding calibrate`): from a test payment or a template (EssentialsX DE/EN, Citybuild).
- **Stronger spoof protection:** death, join and advancement messages, whispers and named mobs/items never count as a payment.
- **Setup with 9 slots** (keys `1`–`9`), duration in one click (30 s – 10 min), hotkeys *Repeat last auction* / *Load as template* (`/bidding repeat [setup]`).
- **Long item names** scroll smoothly instead of being cut off with "…".
- **Lean settings** with six switches, each explained.
- **`/bidding diagnose`:** a short status report to copy if something doesn't work.
- **Hotkeys:** only `J` is bound by default, so nothing clashes with Iris (`K`) or the friends screen (`O`).
- The OBS overlay only answers local requests (`127.0.0.1`/`localhost`).
- Menus now fit small GUI sizes.
