Description

Depends on #625 (merge #625 first) via #616. Merge #616 after #625.

#625 adoption: this PR has no send-dialog mapping of its own. It carries the CFS map panel from #616. Sidebar sync still uses MixedFilamentManager (not filament_is_mixed).

Phase 3 of the Creality send-gap stack (research C6). Sidebar “Sync filaments” on a CFS-capable Creality host reads CFS boxsInfo and applies it through EdgeSlicer’s existing sync path (apply_machine_filament_sync / MixedFilamentManager). The IPrinterAgent framework is not ported (research X1).

Stacked on Phase 2 (cursor/creality-cfs-send-d523). Merge Phase 1 then Phase 2 first.

Does not affect Snapmaker printers (U1 sync is still show_sync_filament_dialog). Needs a Creality K2+CFS hardware smoke. Not a U1 check.

Review 1/3 (B1, F11–F13)

• B1: sync no longer locks the app. /info is checked first (deadline-bound), boxsInfo uses CrealityWsClient, and the progress dialog has a working Cancel.
• F11: the progress title is CFS, not CANVAS.
• F12: the sync button shows only for CFS-capable / K1-family / K2-family models.
• F13: normalize_filament_type maps PCTG → PC and PLA-CF → PLA.

Re-review 1/3 (F20; B3 via #618)

• F20: Cancel aborts the in-flight WebSocket (CrealityWsClient::cancel()). query_boxes_info accepts an optional session pointer. The worker join() waits under a wxBusyCursor.

Re-review 2/3 (B5 via #618, B4 via #616, F24)

• B5: cancel() from this progress dialog is now only an atomic store + net::post(cancel_socket) on the client ioc.
• F24: the cancellable session is constructed after fetch_info so the boxsInfo budget is not spent on HTTP. Step and total timeouts are timeout_s * 1000.

Upstream sources

• OrcaSlicer CrealityPrintAgent::parse_cfs_response / normalize_filament_type / match_filament_preset.
• EdgeSlicer Elegoo CANVAS sync (show_canvas_sync_dialog → FilamentData → apply_machine_filament_sync).

What was adapted

• match_filament_preset takes a FilamentPresetRef list so Catch2 can score it without PresetCollection / IPrinterAgent.
• Sidebar::show_cfs_sync_dialog checks /info, then query_boxes_info, skips the external holder, builds FilamentData, then apply_machine_filament_sync.
• Button tooltip: “Sync filaments from CFS”.
• Never uses filament_is_mixed.

Expected conflicts

• QIDI Box: send the filament-to-slot mapping before starting a print #610 / QIDI send: offer QIDIStudio's print options (Box, leveling, timelapse, polar cooler) #611 / Happy Hare and AFC slot reading for the Moonraker send dialog #612 / Native Moonraker print host (upload without octoprint_compat) #613: Plater.cpp is large; this PR only touches the filament-sync enum, the sidebar button, and show_cfs_sync_dialog.
• Phase 2: this branch already contains it (merged upward).

Untested

• No Creality hardware.
• Catch2 was not compiled here. New sections cover normalize_filament_type and match_filament_preset scoring only.

Tests

Catch2 v2 in printhost_devices_tests.cpp: PLA Silk → PLA, PLA-CF → PLA, PCTG → PC, Hyper PLA wins over Generic PLA. Also carries #616's color_match_from_positions identity test.

Smoke checklist (Creality hardware)

1. K2 + CFS: Sync filaments from CFS → project matches the boxes. Progress title says CFS; Cancel aborts the socket (F20) after /info without a zero boxsInfo budget (F24).
2. Empty CFS: “no loaded slots”; project unchanged.
3. Unreachable printer: /info fails fast; the app stays usable.
4. U1 / Bambu / Elegoo CANVAS sync unchanged.
