🐛 Fix: Slot assignment now properly marks "Aktive Rolle" in Spoolman

When you tapped a slot button (T0–T3) on the DetailScreen, the spool was registered in Spoolman but the per-slot "Aktive Rolle" radio button in the Spoolman web UI stayed empty.

Root cause

The app sent only SET_ACTIVE_SPOOL ID=<id> — a generic command without slot information. The Snapmaker U1 (with the Davo1624 spoolman setup) needs three commands to fully assign and activate a spool on a specific slot. Console-log analysis showed Spoolman itself sends them as three separate API calls — packing them into one multi-line script tripped Klipper's parser in some setups ('T3' is not valid for MACRO).

Fix

The app now sends the three commands as separate /printer/gcode/script POSTs, in the same order Spoolman uses:

1. SET_GCODE_VARIABLE MACRO=T<slot> VARIABLE=spool_id VALUE=<id> — drives the Spoolman UI
2. SAVE_VARIABLE VARIABLE=t<slot>__spool_id VALUE=<id> — persists across Klipper restarts
3. SET_CHANNEL_SPOOL CHANNEL=<slot> ID=<id> — Davo1624 channel state for consumption tracking

Result

• ✅ "Aktive Rolle" radio button updates correctly under the right tool
• ✅ Per-slot consumption tracking maps to the right slot during prints
• ✅ Slot assignment survives Klipper restarts
• ✅ Klipper errors now show as a short, readable snackbar instead of a 100-line Python stack trace

Requirements (printer side)

• Snapmaker official firmware ≥ v1.2.0
• paxx12 SnapmakerU1-Extended-Firmware (e.g. v1.2.0-paxx12-14 or newer) — adds OpenRFID support
• Davo1624 snapmaker-u1 spoolman setup — Klipper macros for per-slot Spoolman mapping
