fix: resolve remaining 19 Python test failures — 285/285 on both runtimes

Script logic fixes (PY mirroring PS1):
- skd-compile: fix (?i) regex flag placement for Python 3.11+
- mxl-compile: handle list-of-lists row format (PS1 silently ignores)
- subsystem-compile: add "objects" → "content" synonym alias
- role-compile: add "rights" → "objects" synonym alias
- meta-compile: sort HTTP/Web service method/operation iteration
- form-edit: insert ChildItems after Events/AutoCommandBar (not at end)
- mxl-compile: sort colWidthMap iteration in both PS1 and PY for
  deterministic format indices
