feat(posts): CI Fiber one program per sheet, configurable pallet change

Browse Source 
Multi-sheet nests previously went into one program with a single header
size and one M50 at the end, so sheet 2 would cut into sheet 1's
skeleton. New Sheets settings:

- One program per sheet (default on): JOB.cnc -> JOB-1.cnc, JOB-2.cnc,
  each a full program with its own size and pallet change (CL-series
  batch rule, EM-423 7.4). Single-sheet nests keep the chosen name.
- Off: one program, with /L "L0" + pallet change between sheets;
  mixed sheet sizes are rejected.
- Pallet change code (default M50, unconfirmed for multi-sheet CI Fiber
  runs; documented as a release blocker).

All sheets are validated and rendered before any file is written.
IMultiFilePostProcessor lets the desktop app confirm overwrites of every
target file and list what was saved, and the console print each file.
