fix(line): use configured field in collectStatusIssues instead of raw token

collectStatusIssues previously checked account.channelAccessToken directly,
but this field is stripped by projectSafeChannelAccountSnapshotFields for
security. This caused 'openclaw status' to always report WARN even when the
token is valid and the LINE provider starts successfully.

Use account.configured instead, which is already computed by
buildChannelAccountSnapshot and correctly reflects whether credentials
are present. This is consistent with how other channels (e.g. Telegram)
implement their status checks.

Fixes #45693
