DMs to unreachable peers use store-and-forward instead of failing instantly (#1415)

* DMs to unreachable peers route through store-and-forward; drop stale reachability gates Field-found: sendPrivateMessage pre-judged reachability and marked the message failed without ever calling the router, so the retained outbox, courier deposits, and bridge drops never ran — a DM composed after a peer's reachability window lapsed was dead on arrival while an identical one sent a minute earlier delivered. Messages now always route; a live path earns "sent", everything else stays "sending" until the router reports carried/delivered or expires it as failed. A sweep for sibling gates found and fixed: - startPrivateChat refused offline non-mutual favorites ("mutual favorite required for offline messaging") — store-and-forward only needs the recipient's noise key, so the gate and its string are gone. - markPrivateMessagesAsRead skipped the whole receipt pass for peers without a stored Nostr key, starving mesh-connected non-favorites; the router picks the transport now (sentReadReceipts dedups the parallel PrivateChatManager path). - DM/geoDM blocked notices and the unknown-group error posted to the active public timeline; they now land in the thread they're about via addLocalPrivateSystemMessage. - Banned copy: literal "user" fallbacks in code become "anon" (the default-nickname convention), and es/fr/it/pt translations of four keys still saying usuario/utilisateur/utente/usuário now say person. Orphaned keys removed (system.dm.unreachable, content.delivery.reason.unreachable, system.chat.requires_favorite). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Deflake BLEServiceCoreTests: longTimeout for positive waits CI flaked on duplicatePacket_isDeduped: the first message landed after the 5s wait expired on a loaded runner (the test's later count==1 assertions passed, proving late delivery, not lost delivery). All four positive waits in the file now use TestConstants.longTimeout, which exists for exactly this — waitUntil returns as soon as the condition holds, so passing runs never pay the longer ceiling. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Fix read-receipt test contamination; baseline Periphery noiseKey flake Two CI failures, both environmental: - markReadReceiptSent_returnsFalseOnSecondCall flaked because every test ChatViewModel shared one per-process read-receipts scratch suite; the lifecycle test persists the same "read-1" ID (a path the receipt-gate removal now reaches), and test order decided who saw whose state. Each instance now gets its own UUID-suffixed suite. - Periphery intermittently misses the loadFromDisk read of PrekeyBundleStore.StoredBundle.noiseKey and fails --strict with a false "assign-only" finding (recurrence of a known flake). Its USR is baselined; an in-source periphery:ignore can't work because strict mode flags it as superfluous on runs where the indexer gets it right.
