[Feature]: Per-job process overrides for server-side slicing

[kahlstrm]

Problem or Use Case

Small per-job slicing changes currently require persistent process presets.

Proposed Solution

Add optional process_overrides to slice requests and merge safe values into the resolved process profile before slicing. Reject profile identity and G-code/script fields.

{
  "process_overrides": {
    "brim_type": "outer_only",
    "brim_width": "6",
    "brim_object_gap": "0.1"
  }
}

Alternatives Considered

One-off presets, brim-specific request fields, and local slicing.
