Add slot action picker to SpoolBuddy AMS page

  Clicking an AMS slot now shows a picker with options: Configure AMS
  Slot, Assign Spool (inventory) or Link to Spoolman, and Unassign/
  Unlink when a mapping exists. Reuses the existing AssignSpoolModal
  and LinkSpoolModal components from the main Bambuddy frontend.

CHANGELOG.md

@@ -11,6 +11,7 @@ All notable changes to Bambuddy will be documented in this file.
 - **External Folder Mounting for File Manager** ([#124](https://github.com/maziggy/bambuddy/issues/124)) — Host directories (NAS shares, USB drives, network storage) can now be mounted into the File Manager without copying files. Click "Link External" to point at a Docker bind-mounted path. Files are indexed into the database on scan but accessed directly from their original location — nothing is copied. Supports read-only mode (default, blocks uploads/moves/deletes), hidden file filtering, and automatic thumbnail extraction for 3MF, STL, gcode, and image files. External folders show a distinct icon and info bar with a rescan button. Deleting an external folder only removes the database index, never the actual files. Requested by @S1N4X.
 
 ### Improved
+- **SpoolBuddy AMS Slot Action Picker** — Clicking an AMS slot on the SpoolBuddy AMS page now shows a picker with contextual actions: Configure AMS Slot (set filament preset, K-profile, color), Assign Spool / Link to Spoolman (depending on which system is active), and Unassign / Unlink when a spool is already mapped. Previously the slot click went straight to the configure modal with no way to assign inventory spools or link Spoolman spools.
 - **SpoolBuddy Settings Device Tab No Longer Scrolls** — Removed the branding card, folded Device ID into the Device Info card, placed Backend/Auth config and diagnostic buttons side by side in a 2-column layout, removed the redundant online/offline status row from Device Info, and tightened spacing throughout. The Device tab now fits on the small SpoolBuddy touchscreen without scrolling.
 - **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/`).
