fix(import): surface real error messages in WordPress import failures

[maikunari]

What does this PR do?

Surfaces real exception messages in WordPress import errors instead of the generic "Failed to import item" string.

Problem

Both WordPress import paths catch per-item exceptions and replace them with a hardcoded "Failed to import item" string before adding them to the result. The actual error message is logged to the server console via console.error, but discarded from the API response.

This makes issues like #553 (where all 185 items failed) nearly impossible to diagnose remotely — every error in the admin UI looks identical regardless of root cause.

Change

Replace the hardcoded string with the actual error.message, falling back to "Failed to import item" only when no message is available:

error: error instanceof Error && error.message
    ? error.message
    : "Failed to import item",

Scope

Intentionally narrow. This does not fix #553 — it makes #553 (and future import failures) diagnosable so the root cause can be identified from user reports.
