Walkthrough

This PR updates nostr-sdk and mostro-core dependencies, then systematically migrates all timestamp conversions across utility modules from the older as_u64() method to the newer as_secs() API. The changes are applied consistently to chat gift wraps, direct messages, instance metadata, and order parsing.

Changes

Timestamp API Modernization

Layer / File(s)	Summary
Dependency Version Updates Cargo.toml	mostro-core bumped to 0.10.1 and nostr-sdk bumped to 0.44.1 with existing feature flags preserved.
Chat Gift Wrap Timestamp Conversions src/util/chat_utils.rs	unwrap_giftwrap_with_shared_key and fetch_gift_wraps_for_shared_key now use as_secs() for inner event timestamps and 7-day lookback window computation.
DM Utility Timestamp Migrations src/util/dm_utils/dm_helpers.rs, src/util/dm_utils/mod.rs	ensure_order_giftwrap_subscription fallback, parse_dm_events filtering, and fetch_and_replay_startup_trade_dms cursor calculations all converted to as_secs().
Instance Info and Order Timestamp Conversions src/util/mostro_info.rs, src/util/order_utils/helper.rs	Instance stale checks via format_instance_info_age and is_stale, plus parse_disputes_events and parse_orders_events now use as_secs() for all timestamp assignments.

Poem

🐰 Timestamps hop through time anew,
From as_u64() to seconds true,
Each utility sings in harmony,
With nostr-sdk's symphony! 🎵
