ws040: deliver name-less card reply by resolving its sidebar row (real fix)

Root cause of the card stall (confirmed via ws038/039 probe + live DOM): a
name-less card dispatches under a synthetic 'card:<conv>' name (ws033c), but
feige_send_message matches the sidebar row BY NAME, and the real row is 'sc'
-> "Session not found" -> requeue loop. There is NO shared id to map the WS
card to its DOM row: the row exposes only name + btm tracking ids + avatar; the
talk_id/uid appear nowhere on it, and the display name is DOM/HTTP-only (the
avatar uid is in an HTTP answerRecommend call, not WS).

Fix: when the synthetic 'card:' name can't be matched, resolve the card's
conversation ROW directly — the UNIQUE sidebar row whose preview starts '[商品'
AND whose class has 'needReply'. If exactly one -> deliver to its real name
(rebind expectedCustomer so all crosstalk guards verify the actual conv). If 0
or >1 -> fall through to not-found + requeue (NEVER guess -> mis-delivery-safe).
Gated to synthetic 'card:' names only; named-customer + text delivery untouched.

Selectors verified against the live sidebar DOM (msgContent '[商品]',
nameLine/newNameContent 'sc', needReply-* class). Needs a live run to confirm
the full send flow (browser JS can't be simulated offline).
