[Client] Tell the user when their playmat art is blocked (#7533)

Browse source 
* [Client] Tell the user when their playmat art is blocked

A server DENY rule silently drops banned playmat art: SetPlaymat fails
with no handler and DeckSelect strips the mat while answering RespOk.

Surface both cases with the same critical message box the banner card
art flow uses. DeckSelect strips are detected by comparing the
requested mat, passed via PendingCommand extraData, against the
server-echoed deck. Notices dedupe per card and reset on success.

* [Client] Gate playmat blocked notice on RespFunctionNotAllowed per review

Only SetPlaymat with RespFunctionNotAllowed signals a card art DENY
rule. Older servers answer RespInvalidCommand and strip the mat from
DeckSelect, so drop the DeckSelect comparison to avoid false
blacklisted popups on pre-playmat servers.
