Mesh robustness optimizations (#463)

* Mesh robustness: link-aware fragmentation, relay jitter, connection budget, adaptive scanning; fix BLE queue deadlock - Link-aware fragmentation using per-link write/notify limits - Directed fragments for one-to-one; exclude from relays - Add relay jitter with cancel-on-duplicate to reduce floods - Cap central links and rate-limit connect attempts with queue - Foreground duty-cycled scanning when connected; continuous when isolated - Fix deadlock by avoiding sync on BLE queue when already on it - Silence Keychain var->let warnings * Mesh: add relay jitter; dynamic RSSI threshold; candidate scoring/backoff; fix misplaced lines in BLEService extension * macOS UI: restore mesh peer list when geohash feature is iOS-only by moving mesh list outside iOS switch (ContentView) * ContentView: add macOS mesh peer list under #else to fix missing People section on macOS * Refactor People section: extract MeshPeerList and GeohashPeopleList into separate views to reduce SwiftUI type-checking complexity; integrate in ContentView * BLE: prevent re-fragmentation loops; UI: darker mesh blue + first-row spacing in peer list * Mesh flood/battery: probabilistic relays, adaptive TTL caps, fragment pacing + scan pause, assembly cap; enable relayed DMs with direct-first then flood fallback. * Refactor BLEService broadcast: split pad policy, encrypted/direct-first handler, and link-aware sender; simplify broadcastPacket to delegate by type. * Extract relay decision into RelayController with RelayDecision; simplify handleReceivedPacket to use it. * Move RelayController and RelayDecision into their own file under Services; keep BLEService leaner. * UI: adjust mesh blue to a darker, less purple tone; apply consistently for count and #mesh badge. * Project: include RelayController.swift in target and sync project file changes. --------- Co-authored-by: jack <jackjackbits@users.noreply.github.com>
