feat(mining): migrate the Windows Defender antivirus-help dialog to reference design

Bring renderAntivirusHelpDialog onto the reference design and remove its hardcoded
English (the last Wave-1 modal):
- struct-form BeginOverlayDialog(OverlayDialogSpec{BlurFloat, cardWidth 560,
  idSuffix antivirus}) replacing the legacy positional overload
- the hardcoded "Windows Defender Blocked Miner" title and all 10 step/intro/bullet
  strings -> TR() (11 new av_* keys + reuse `close`; 8-lang translations, Windows
  env vars / xmrig.exe kept literal, menu names localized)
- 2 StyledButton -> TactileButton, drop the footer divider, dp-scale the button widths
- CJK subset rebuilt (glyphs 1741->1751; kept — new glyphs are used)

NOTE: this dialog is inside #ifdef _WIN32, so the Linux build compiles it out and
cannot verify it — needs a Windows build to compile-check. The edits mirror the
already-verified daemon-update-prompt / migrate-to-seed struct-overlay pattern and
leave the ShellExecuteA call untouched. i18n.cpp + the daemon prompt (cross-platform)
build + ctest + hygiene clean on Linux.
