Lower minimum supported Memos to v0.15.0

Update compatibility range to include Memos v0.15.0 across README and locale files (en, ja, ko, zh_CN). Bump manifest version/date to 2026.03.12 and update version_name to reflect the new supported range. This extends backward compatibility to older Memos releases.
