When a user creates a new filament preset by inheriting from an
existing one (e.g., "Brand ABS @BBL H2D" inheriting from "Generic
ABS @BBL H2D"), the resulting preset previously had no filament_id
of its own. This caused two problems:
1. The AMS sync pipeline could not distinguish the user preset from
its parent, so syncing filaments from the printer always resolved
to the generic base preset instead of the user's custom one.
2. External tools that rely on filament_id for preset identification
(e.g., Bambuddy, see maziggy/bambuddy#1053) could not assign or
recognize user-created inherited presets in AMS slots.
The root cause was twofold:
- No filament_id was generated during save_current_preset() for
inherited filament presets. Only base (non-inheriting) presets
received one via the CreatePresetsDialog flow.
- The AMS matching logic in sync_ams_list(), get_ams_cobox_infos(),
and get_filament_presets() filtered candidates with
`get_preset_base(f) == &f`, which by definition excludes any
preset with a non-empty inherits() field.
This commit:
- Generates a unique filament_id (MD5 hash of preset name, prefixed
with "P", truncated to 8 chars) when creating a new filament
preset in PresetCollection::save_current_preset(). This matches
the existing ID generation scheme used for base filaments in
CreatePresetsDialog::get_filament_id().
- Persists filament_id into the JSON when saving inherited presets
via Preset::save() and get_differed_values_to_update().
- Broadens the AMS filament matching predicates to also consider
user presets that carry their own filament_id, rather than
requiring them to be base presets.

# Description
This pull request fixes the bug where Orca Slicer enters an infinite
loop when a density of zero is introduced for the top layer solid infill

Note: For bottom solid infill, this is not a problem because the minimum
density is 10%.
Makes sure all non-bbl printers go through the same filament reordering
code so custom filament sequence is properly handled, while skipping the
filament grouping part by mapping all filaments to group 0.
This is the same method used by BBL printer to calculate the optimal
filament grouping so should be robust.
Fix#12449Fix#12766
Previously, wipe tower behavior was determined by checking if the printer
was a QIDI vendor. This introduces a configurable enum (Type 1 / Type 2)
so any printer can select its wipe tower implementation. BBL printers
remain hardcoded to Type 1. Qidi profiles default to Type 1.
Add a guard that skips creating fill params for top surfaces when the configured density is less than or equal to zero. This avoids generating surface fills for zero/negative densities and prevents unnecessary processing or potential errors when top surface density is disabled.
When flush_multiplier is applied to flush_volumes_matrix values, the
result can be a decimal (e.g., 272 * 1.3 = 353.6). Some printer firmware
metadata parsers (notably Creality K2) crash when parsing decimal values
in flush_volumes_matrix, causing prints to get stuck at "File selected".
This fix rounds the multiplied values to integers, ensuring compatibility
with firmware that expects integer values in this field.
Fixes compatibility with Creality K2 and potentially other Klipper-based
printers that parse the CONFIG_BLOCK metadata.

The WipeTower2 code path never called construct_mesh(), leaving
wipe_tower_mesh_data as std::nullopt. GCode export then dereferenced
it unconditionally, triggering an assertion failure / crash.
1. Dirty flags not showing for extruder options:
2. Crash when switching to non-first extruder tabs:
3. Modifying one extruder's parameter affects other extruders:
Fix crash in PA calibration pattern generation
Reset current extruder ID and clear pointers in set_extruders to prevent dangling pointers when extruders are recreated. Also fixed undefined behavior by checking if the vector is empty before taking max_element.

## Summary
- Change default bed temperature type from "By First filament" to "By Highest Temp"
- Move `bed_temperature_formula` option from develop mode to advanced mode for better accessibility
- Relocate UI control from "Basic Information - Advanced" to "Multimaterial Setup" section where it's more relevant for multi-filament printing
Using the highest temperature of all printed filaments is generally safer for bed adhesion than using the first filament's temperature, especially in multi-material prints where different filaments may require different bed temperatures.

# Description
This PR enhances the GCodeProcessor's time estimation by incorporating Junction Deviation (JD) into the jerk calculations, providing more accurate print time predictions for firmwares that use JD (like modern Marlin).
Key Changes:
- Added JD support to time estimation
- Reads machine_max_junction_deviation (machine limits) and default_junction_deviation (print profile)
- When JD is enabled (>0), replaces traditional X/Y jerk values with JD-based calculation:
$Jerk = \sqrt{2.5\cdot JD \cdot acceleration }$
- Falls back to traditional jerk when JD is not used
# Test:
JD:0.0256mm Accel.: 1000 mm/s²
