fix: social gate round 2, part 2 - confirmation-dialog sentences + the

refused-drop yellow notice

Item 4 (confirmation dialogs missing text + names): the missing retail
mechanism was StringTable template substitution - an entry is N+1 literal
fragments interleaved with N named variables, composed by
StringTable::GetString @0x004300D0 (no-metalanguage branch @0x004303B7).
ACE sends the bare player name for types 1/4; retail's OWN CLIENT wraps
it. Ported as DatStringResolver.ResolveTemplate (PLAYER hash 0x05506DA2,
the exact compute_str_hash space; Chorizite stores the variable hashes
directly):

- Server-driven type 4 -> ID_Fellowship_FellowshipRequest, type 1 ->
  ID_Allegiance_AcceptSwearConfirmation, injected into
  GameplayConfirmationController; null resolve falls back to the bare
  wire message, never invented English. The 2/3/5/6 " Continue?" family
  never consults the composer.
- Local Swear/Break/Kick: the bind-time fragment-0 latch (which showed
  the dangling "Do you wish to swear to ") is replaced by click-time
  ResolveTemplate with the target's name.

All five templates verified token-free in the installed DAT - this is
NOT a StringTableMetaLanguage port (AD-81's engine caveat stands).

Item 5 (refused drop shows nothing; retail shows yellow top-center
text): the prevRequest latch was ALREADY ported (InventoryTransactionState);
what was missing was the consumer. InventoryTransactionState now raises
RequestFailed(request, weenieError) when a 0x00A0 clears the latch;
ItemInteractionController composes ServerSaysAttemptFailed @0x0058EAE0's
"The <item> can't be <verb>" (verb table + suffix map ported verbatim in
Core's InventoryFailureMessages, NAME_PLURAL for merge/split) and routes
it as LogTextType 0x1A ClientLocal -> the SpewBox, retail's yellow
top-center line. The dispatcher's second leg (@0x0055B342) also runs:
outside the 7-code exclusion set, WeenieErrorMessages resolves per-code
text/destination; 0x426 AttunedItem has no row in either place beyond
the verb line - faithful single-line output.

Register: AD-85 narrowed to its numeric-field item, AD-81 amended (the
token-free interleave is now ported; meta-token engine + FormatName
remain), AD-93 filed (wire-guid-match vs retail's latched-guid
preference; no Move/Wield latch kinds).

Tests: +2 InventoryTransactionState failure-latch, +5 ResolveTemplate
(constructed StringTable fixtures), +1 composer injection, +1 end-to-end
refused-drop line. Core 4,697/1 skip, App 4,983/3 skips.
