Raise the chamber-temperature ceiling from 60 to 65 C

Every field that takes a chamber target stopped at 60: the per-filament
    chamber map and per-print override in Preheat & Heat Soak, the chamber
    quick-select presets, and the printer-card chamber control. 60 is the
    X1E's ceiling and the X1E was the only heated-chamber model when that
    limit was written; the H2 series and X2D heat to 65, so the top of their
    range was unreachable.

    The ceiling now lives in one constant per side (MAX_CHAMBER_TEMP_C in
    backend/app/utils/printer_models.py and frontend/src/utils/printer.ts)
    rather than as a literal at each call site. X1E firmware clamps a higher
    request to its own maximum, so a shared ceiling is safe.

    Also fixes a live bug at PrintersPage.tsx:7985: parsePresetTriple was
    bounded to 60 there, and it rejects the whole triple on any out-of-range
    entry, so a saved 65 preset would have silently reverted the printer
    card to the defaults while Settings still showed 65.
