Add FilAr filament vendor (PLA, PLA-mate, PETG)

This PR adds FilAr, an Argentine filament manufacturer (https://www.filar.com.ar), as a system filament vendor for Bambu Lab printers.

What's included

For each of the three materials (PLA, PLA-mate, PETG):

• 1 non-instantiated @base profile inheriting from fdm_filament_pla / fdm_filament_pet.
• 13 printer-specific presets covering the same machine set as the existing third-party eSUN PLA+ line: A1, A1 mini, X1, X1 Carbon / P1S / X1E, H2D, H2D Pro, H2S (with 0.2 nozzle variants).
• All 42 presets registered in resources/profiles/BBL.json → filament_list.

Files live under resources/profiles/BBL/filament/FilAr/ (following the SUNLU/ sub-folder convention).

Profile parameters (per manufacturer datasheet)

Material	Nozzle	Range	Bed
PLA	210 °C (init 215)	200–220	60 °C
PLA-mate	200 °C (init 205)	195–210	60 °C
PETG	240 °C (init 245)	230–250	78 °C, reduced part cooling (40–60%)

Density: PLA 1.24, PETG 1.27 g/cm³. The per-printer mechanical tuning (fan curves, max volumetric speed, plate handling, dual-extruder includes) is inherited from Bambu's own eSUN PLA+ (PLA/PLA-mate) and Generic PETG (PETG) presets, so behavior matches established profiles; only the material identity and temperatures reflect FilAr's datasheet.

⚠️ Notes for maintainers (please read)

• filament_id / setting_id are placeholders (FILARPLA, FILARPLA_00, …). I don't have officially assigned Bambu IDs. They are unique and pass check_duplicated_setting_id.py, but please reassign them to the proper registry values before merging if required — happy to update.
• Temperatures are the manufacturer's published baseline ranges, not per-printer calibrated. I'm glad to refine any value or add calibration evidence on request.
• Scope mirrors the existing eSUN PLA+ coverage. P1P / H2C / P2S / X2D are not included yet (same as eSUN) but can be added if desired.
• Colors are not enumerated as separate presets (Bambu convention for third-party brands); color is selected by the user.
