Flux Network Recreated

## 8.0.0 — First NeoForge 26.1.2 release

First release of Flux Networks for **Minecraft 26.1.2** and **NeoForge 26.1.2.116+**, ported from the 1.20.1 Forge version (7.2.1).

### New
- **Completely redesigned interface**: dark theme, sidebar navigation, live values, notifications and confirmation dialogs.
- **Connections tab**: select several devices and edit their priority, limit, surge mode, unlimited mode and chunk loading in one go.
- **Statistics tab**: device counts, input/output, stored energy, tick time and a 1-minute transfer history chart.
- **Members tab**: members and online players in separate lists, with promote, demote, remove and transfer ownership actions.
- **Network creation and settings**: colour presets plus custom hex colour, with a live preview.
- **Wireless charging of the main inventory** (in addition to main hand, off hand, hotbar and armor).
- The **Flux Configurator** screen can now store priority, limit, surge and unlimited settings to paste onto devices.
- Several players can open the same device at the same time.
- Interface adapts to small windows (icon-only sidebar).
- Full **English** and **French** translations.
- `/fluxnetworks superadmin <players> <true|false>` command.

### Changed
- Energy now uses NeoForge's transactional energy API: works with any mod using FE.
- Storage energy gauges are rendered with the 26.1 renderer and keep the network colour.
- Device settings are kept on the dropped item (data components), and storages keep their energy when upgraded or reset in the crafting grid.
- Every action from the interface is validated again on the server (access level, distance to the device, item in hand).
- Configuration file: `serverconfig/fluxnetworks-server.toml` (same options as before).

### Removed
- Integrations with Mekanism, GregTech, IC2, OpenComputers, The One Probe, Curios, JEI and Modern UI.
- Curios slot charging (replaced by main inventory charging).
- The original GUI textures and sounds (the new interface uses original icons and artwork).

### Notes
- Worlds and items from 1.20.1 are not converted.
- Item models of the Flux Plug and Flux Point now show the core only.
