Per @SoftFever review on #13752, printer-specific filament sync logic
belongs in the agent rather than in Sidebar. This consolidates the
previously-duplicated code so all CFS-specific work lives in
CrealityPrintAgent.
Changes:
- New: CrealityPrintAgent::sync_filaments_into_ams_list() — static method
that builds a CrealityPrint host from a printer_cfg, queries CFS slots,
populates PresetBundle::filament_ams_list, and triggers sync_ams_list().
GUI-free; returns a result struct (Status + counts + detail) so the
caller decides what dialog to show.
- New: nested CFSAmsListResult struct describing the five possible
outcomes (Success / NotCfsCapable / QueryFailed / EmptySlots / NoMatches).
- Removed: Sidebar::sync_filaments_from_creality_cfs() entirely (its body
is now the agent method).
- Plater.hpp loses the declaration; Plater.cpp dispatches to the agent
inline within sync_ams_list() and owns only the dialog + post-sync UI
refresh (combo updates, layout, preset selection, persistence).
Two CFS-related entry points on the agent now coexist:
- fetch_filament_info() — agent-driven path; publishes via AmsTrayData
and build_ams_payload(). Active when a MachineObject is bound (BBL
concept, not currently created for Creality LAN hosts).
- sync_filaments_into_ams_list() — explicit-pull path used today by the
Sidebar's "Sync filaments" button until the K-series MachineObject
work catches up.
No user-visible behaviour change — same end-to-end flow, the data work
just lives in the agent now.
