WalkthroughThis change refactors the dispute chat system by introducing a UI-friendly DisputeChatMessage wrapper containing NostrEvent with pending/error state, replacing raw DisputeChat usage. The implementation switches to single-layer p2pWrap encryption, adds persistent storage for encrypted gift-wrap events, and updates related widgets and services accordingly. Changes

- Line 28: The timestamp getter currently falls back to DateTime.now() which
yields non-deterministic ordering; change the fallback in the timestamp getter
(DateTime get timestamp) to a deterministic value such as
DateTime.fromMillisecondsSinceEpoch(0) or another stable field on event (e.g.,
event.updatedAt or an event ID-derived timestamp) instead of DateTime.now(),
leaving the primary use of event.createdAt intact.

…ring bug - Per-message send errors now stay at message level only - Removed state.error propagation from _updateMessageState - Prevents full-chat error overlay on individual message failures

Clean refactor that properly unifies the dispute chat model with the P2P chat pattern. Key improvements:
- Encrypted storage: Storing gift wraps (encrypted) on disk instead of decrypted content is the correct approach — consistent with P2P chat and better for privacy.
- DisputeChatMessage wrapper: Thin, focused wrapper around NostrEvent with UI-only state (pending/error) — good separation of concerns.
isFromUser()via pubkey comparison: Better than storingis_from_userflag — single source of truth._updateMessageState()extraction: Eliminates significant duplication in error handling paths.getAdminSharedKey(): Good forward-thinking for Phase 3 multimedia.
CI passes, no conflicts, no unresolved comments. LGTM ✅
