maziggy 6507fbcc40 fix(slicer): surface real CLI rejections + hard-skip mismatched filaments in auto-pick (#1851)
Two compounding bugs let an H2C-bound filament land in slot 1 of an A1
    slice silently. (1) `_slicer_rejection_message` discarded the actual CLI
    diagnostic - `filament preset Generic PLA @BBL H2C (slot 1) is not
    compatible with printer Bambu Lab A1 0.4 nozzle.` - when the sidecar's
    headline error_string was Bambu Studio's catch-all
    `The input preset file is invalid and can not be parsed.` placeholder.
    The real reason was in the stdout `[error] run NNNN:` line, trimmed off
    before reaching the SliceJob's error_detail. (2) `pickFilamentForSlot`
    used a soft `-100` mismatch penalty rather than a hard skip, leaving
    the "never auto-fill an incompatible preset while a compatible one
    exists" contract implicit. The unused-slot substitution in
    `substitute_unused_plate_filaments` then propagated whatever slot 1
    held across every unused slot - one bad pick poisoned the array.

    (1) Mine `[error] <msg>` (with or without `run NNNN:`) from the full
    pre-trim response; substitute the placeholder, keep meaningful
    headlines. (2) Partition candidates into compatible/unknown vs
    mismatch; prefer compatible whenever the bucket is non-empty, fall
    back to mismatch only on graceful-degrade. Picker helpers moved out
    of `SliceModal.tsx` into `utils/slicePresetPicker.ts` so the modal
    file stays component-only (react-refresh lint).
