Add iPad support, auto-pinning, and comprehensive logging

- Adaptive iPhone/iPad layout with NavigationSplitView sidebar
- Auto-detect SSL-pinned domains, fall back to passthrough
- Certificate install via local HTTP server (Safari profile flow)
- App Group-backed CA, per-domain leaf cert LRU cache
- DB-backed config repository, Darwin notification throttling
- Rules engine, breakpoint rules, pinned domain tracking
- os.Logger instrumentation across tunnel/proxy/mitm/capture/cert/rules/db/ipc/ui
- Fix dyld framework embed, race conditions, thread safety
