Fix maintenance tasks showing wrong rod type for printer models (#351)

H2/A1 series have linear rails, not carbon rods. X1/P1/P2S have carbon rods, not linear rails. Split rod-specific maintenance into model-aware pairs: "Lubricate/Clean Carbon Rods" for X1/P1/P2S and "Lubricate/Clean Linear Rails" for A1/H2. Added rod type classification to printer_models and startup cleanup for stale/duplicate system maintenance types.

 - **Nozzle-Aware AMS Filament Mapping for Dual-Nozzle Printers** ([#318](https://github.com/maziggy/bambuddy/issues/318)) — On dual-nozzle printers (H2D, H2D Pro), each AMS unit is physically connected to either the left or right nozzle. Bambuddy now reads nozzle assignments from the 3MF file (`filament_nozzle_map` + `physical_extruder_map` in `project_settings.config`) and constrains filament matching to only AMS trays connected to the correct nozzle via `ams_extruder_map`. Applies to the print scheduler, reprint modal, queue modal, and multi-printer selection. Falls back gracefully to unfiltered matching when no trays exist on the target nozzle. The filament mapping UI shows L/R nozzle badges for dual-nozzle prints. Translated in all 4 locales (en, de, ja, it).

 ### Fixed
+- **Model-Specific Maintenance Tasks for Carbon Rods vs Linear Rails** ([#351](https://github.com/maziggy/bambuddy/issues/351)) — Maintenance tasks "Clean Carbon Rods" and "Lubricate Linear Rails" were shown for all printers regardless of motion system. H2 and A1 series use linear rails (not carbon rods), and X1/P1/P2S series use carbon rods (not linear rails). Maintenance types are now classified by rod/rail type: "Lubricate Carbon Rods" and "Clean Carbon Rods" for X1/P1/P2S, "Lubricate Linear Rails" and "Clean Linear Rails" for A1/H2. Stale and duplicate system types are automatically cleaned up on startup. Includes model-specific wiki links and i18n keys for all 4 locales.
 - **AMS Slot Configuration Overwritten on Startup** — Bambuddy was resetting AMS slot filament presets on every startup and reconnection. The `on_ams_change` callback unconditionally unlinked Bambu Lab spool assignments on each MQTT push-all response, then re-assigned them by sending `ams_filament_setting` without a `setting_id`, which cleared the printer's filament preset. Now compares spool RFID identifiers (`tray_uuid` / `tag_uid`) before unlinking — if the same spool is still in the slot, the assignment is preserved and no `ams_filament_setting` command is sent.
 - **Bambu Lab Spool Detection False Positives** — The `is_bambu_lab_spool()` function (backend) and `isBambuLabSpool()` (frontend) incorrectly identified third-party spools as Bambu Lab spools when they used Bambu generic filament presets (e.g., "Generic PLA"). The `tray_info_idx` field (e.g., "GFA00") identifies the filament *type*, not the spool manufacturer — third-party spools using Bambu presets also have GF-prefixed values. Removed `tray_info_idx` from detection logic; now uses only hardware RFID identifiers (`tray_uuid` and `tag_uid`) which are physically embedded in genuine Bambu Lab spools.
 - **FTP Disconnect Raises EOFError When Server Dies** — `BambuFTPClient.disconnect()` only caught `OSError` and `ftplib.Error`, but `quit()` raises `EOFError` when the server has closed the connection mid-session. `EOFError` is not a subclass of either, so it propagated to callers. Now caught alongside the other exception types for clean best-effort disconnect.
