enh: flow rate pattern calibration menu (#11956)

* feat: Add flow rate calibration pattern selector dialog

* feat: Integrate PR #11881 and improve Flow Rate Calibration Wizard

- Integrated PR #11881: Display layer duration in G-code viewer position window.
- Enhanced Flow Rate Calibration:
    - Implemented a Wizard dialog (FlowRateCalibrationDialog) using DPIDialog for Dark Mode support.
    - Restricted pattern selection to 'Archimedean Chords' and 'Monotonic'.
    - Integrated logic to pass the selected pattern to the calibration generation.

* fix(UI): Refactor FlowRateCalibrationDialog to calib_dlg for macOS build fix and UI consistency

Moved FlowRateCalibrationDialog from MainFrame.cpp to calib_dlg.hpp/.cpp to resolve build errors on macOS. Updated UI to match Pressure Advance calibration dialog style (Dark Mode support, RadioGroups). Logic moved to dialog class.

* Update Wiki link for flow rate calibration

* ui: replace RadioGroup with BitmapComboBox for Flow Rate pattern selection

* fix(ui): use custom ComboBox widget for Flow Rate Calibration

Replaces wxBitmapComboBox with OrcaSlicer's custom ComboBox widget to fix rendering issues on Windows (empty selection) and compilation errors on Linux.

* Refactor: Cleanup unused includes and members in FlowRate calibration dialog

* Fix: Complete rename of Flow Rate to Flow ratio in calibration menus after merge

* Fix: Update Flow Rate to Flow Ratio in Calibration Dialog and Wiki Link
