fix: Windows identity, async address creation, mining UI, and chart artifacts

Windows identity:
- Add VERSIONINFO resource (.rc) with ObsidianDragon file description
- Embed application manifest for DPI awareness and shell identity
- Patch libwinpthread/libpthread to remove competing VERSIONINFO
- Set AppUserModelID and HWND property store to override Task Manager cache
- Link patched pthread libs to eliminate "POSIX WinThreads" description

Address creation (+New button):
- Move z_getnewaddress/getnewaddress off UI thread to async worker
- Inject new address into state immediately for instant UI selection
- Trigger background refresh for balance updates

Mining tab:
- Add pool mining dropdown with saved URLs/workers and bookmarks
- Add solo mining log panel from daemon output with chart/log toggle
- Fix toggle button cursor (render after InputTextMultiline)
- Auto-restart miner on pool config change
- Migrate default pool URL to include stratum port

Transactions:
- Sort pending (0-conf) transactions to top of history
- Fall back to timereceived when timestamp is missing

Shutdown:
- Replace blocking sleep_for calls with 100ms polling loops
- Check shutting_down_ flag throughout daemon restart/bootstrap flows
- Reduce daemon stop timeout from 30s to 10s

Other:
- Fix market chart fill artifact (single concave polygon vs per-segment quads)
- Add bootstrap checksum verification state display
- Rename daemon client identifier to ObsidianDragon
