Add material/profile mismatch warnings to SpoolBuddy Assign-to-AMS modal

  The AssignToAmsModal was missing all material/profile validation guards
  that exist in the main AssignSpoolModal. Clicking an AMS slot now checks
  the spool's material and slicer profile against the target slot's current
  filament, showing a confirmation dialog on mismatch. Respects the global
  disable_filament_warnings setting. Uses existing i18n keys and ConfirmModal.

 - **Spool Notes in Assign Spool Modal** ([#793](https://github.com/maziggy/bambuddy/issues/793)) — Spool cards in the Assign Spool modal now show the spool's note as a hover tooltip, making it easier to identify spools by tracking IDs or other metadata stored in notes. Works with both internal inventory and Spoolman-synced spools. Requested by @LegionCanadian.
 - **WiFi Safeguard for SpoolBuddy Pi** — The install script now drops an APT hook (`/etc/apt/apt.conf.d/80-preserve-wifi`) that backs up NetworkManager WiFi connections before every `apt upgrade` and restores them if they get wiped. Prevents headless SpoolBuddy Pis from losing WiFi connectivity after Raspberry Pi OS package upgrades (observed with Bookworm kernel/raspi-config updates that clear `/etc/NetworkManager/system-connections/`).
 - **SpoolBuddy Install Script Now Upgrades System Packages** — The install script now runs `apt-get upgrade -y` after installing required packages and the WiFi safeguard. This ensures the Pi is fully up to date before SpoolBuddy is deployed, and the WiFi safeguard protects connectivity during the upgrade.
+- **SpoolBuddy Assign-to-AMS Material Mismatch Warnings** — The SpoolBuddy "Assign to AMS" modal now warns when the spool's material or slicer profile doesn't match the target slot's current filament. Shows a confirmation dialog with five warning levels: exact material mismatch, partial material match, profile-only mismatch, and combined material+profile mismatches. Respects the global `disable_filament_warnings` setting. Previously, assigning a spool to an occupied slot proceeded without any validation, matching the behavior already present in the main Assign Spool modal.
 
 ### Fixed
 - **Delete Tag Leaves Stale Tag Type** — The "Delete Tag" button in the spool edit modal only cleared `tag_uid` but left `tray_uuid`, `tag_type`, and `data_origin` intact. All tag-related fields are now cleared together.
