British Fill Units
Version 1.3 — Multiplayer & Display Integrity Update

Improvements
- Declared multiplayer support in modDesc.xml.
- Added one authoritative runtime lifecycle for single-player, multiplayer hosts,
  multiplayer clients and dedicated servers.
- Delayed hook registration until all BFU modules have loaded.
- Added clear runtime and subsystem status messages to log.txt.
- Retained the v1.2 trailer configuration fix so each body uses its exact
  base-game store capacity.

Fixes
- Replaced the English-only Prices-page detector with language-independent GUI
  structure detection and localised-header fallback detection.
- Fixed £/t, £/1,000 L, station indicators and the Price Trend guide failing to
  activate for players using non-English game languages.
- Prevented a headless server from requiring client GUI elements.
- Kept all conversion and HUD presentation local to each connected client; no
  savegame or gameplay state is synchronised by BFU.

Test focus
- Single-player Prices page in English and one non-English language.
- Multiplayer host and joining client with the same BFU zip.
- Dedicated-server startup and client join.
- Solid crop station prices, liquid prices, seasonal graph and trend guide.
- Grain/silage trailer body capacities in the shop.
