Implement all five guild_chat attachment endpoints:
- add_deck: server looks up deck by (viewerId, format, deckNo) and snapshots
the current state into a DECK-type chat message DeckPayload column.
- delete_deck: author OR leader/sub-leader may clear; returns refreshed
deck_log. Extended IGuildChatMessageRepository.ClearDeckAsync with
leaderOverride flag; added GetDeckMessagesAsync + GetByMessageIdAsync.
- add_replay: stores {"battle_id": N} in ReplayPayload; full shape is
TODO(post-merge) pending replay-subsystem capture.
- replay_detail: returns the stored ReplayPayload as JsonElement passthrough.
- deck_log: returns all active DECK messages grouped by API-side Format string
key ("1"=Rotation, "2"=Unlimited, "3"=PreRotation always present;
"4"=Crossover, "5"=MyRotation only when non-empty).
Adds DeckLogDataDto (typed) for deck_log / delete_deck responses.
Replay response uses JsonElement passthrough (TODO(post-merge)).
8 new integration tests — all green. Full suite 1530/1530 pass.

Add ChatUserProfile record and IViewerRepository.LoadChatProfilesAsync (AsNoTracking,
projects Name/EmblemId/CountryCode/Rank/DegreeId from Viewer+Info nav refs).
GuildChatController.Messages now injects IViewerRepository instead of SVSimDbContext;
calls LoadChatProfilesAsync to populate users[] (removes direct db access from controller).
GuildChatMessageRepository direction=2 (NEW): change >= start to > start (exclusive).
GuildChatPollTests updated to assert the start message is NOT returned by direction=NEW.
