fix(db-load-xml): surface silent platform rejections + opt-in -StrictLog

Platform writes load-time property/type/enum rejections ("Неверное
свойство объекта метаданных", "Неизвестное имя типа" и т.п.) into the
/Out log but still exits with code 0, silently dropping the offending
metadata. db-load-xml now parses the log for these patterns and prints
a yellow "[warning] N rejection(s)" block to stdout so users (and the
model) can see them immediately.

Exit code still mirrors the platform by default — we don't second-guess
its verdict. With the new -StrictLog switch, rejection patterns are
elevated to exit code 1, which is the mode verify-snapshots.mjs uses
for honest E2E verdicts. All three db-load-xml call sites in the
verifier (main config, CFE base, CFE extension) now pass -StrictLog.

Found while investigating upload/form-baseline/gotchas.md #4 where AR
attribute emission was wrong but verify-snapshots showed green because
the old exit-code-only check missed the silent drops.

Bumped db-load-xml.ps1 + .py to v1.3.
