Dynamic imports of modules with syntax errors currently reject with a stack that points into the ESM loader instead of the module source. The compile path already records the source excerpt, but this error is raised before a ModuleJob can decorate the stack.

Decorate translator errors at the loader boundary and cover a caught dynamic import so the filename, line, and source location are retained.

Fixes: #49441

Validation on macOS after rebasing onto main at 768315c:

• The regression test fails on the main build and passes with this patch.
• python3 tools/test.py --mode=release -j6 -t60 -p tap es-module: 248 passed, 1 Windows-only test skipped.
• ESLint for both changed files passed.
• Repeated imports retain a single source excerpt per error; runtime errors retain their message.

Sorry about that - didn't follow the one-issue-at-a-time guideline. Closing this for now and focusing on #64627 first, will reopen once that's merged.
