Support Memos v0.27 and improve API parsing

Bump supported Memos version to v0.27 across locales, README changelog, and manifest (version and version_name). Improve memos API compatibility: prefer and return trimmed username when present, handle non-numeric trailing name segments safely, and encode userid in the user-scoped memos URL to avoid issues with special characters.
