Mikhail Chusavitin 20f834aa96 feat: v3.4 — boot reliability, log readability, USB export, screen resolution, GRUB UEFI fix, memtest, KVM console stability
Web UI / logs:
- Strip ANSI escape codes and handle \r (progress bars) in task log output
- Add USB export API + UI card on Export page (list removable devices, write audit JSON or support bundle)
- Add Display Resolution card in Tools (xrandr-based, per-output mode selector)
- Dashboard: audit status banner with auto-reload when audit task completes

Boot & install:
- bee-web starts immediately with no dependencies (was blocked by audit + network)
- bee-audit.service redesigned: waits for bee-web healthz, sleeps 60s, enqueues audit via /api/audit/run (task system)
- bee-install: fix GRUB UEFI — grub-install exit code was silently ignored (|| true); add --no-nvram fallback; always copy EFI/BOOT/BOOTX64.EFI fallback path
- Add grub-efi-amd64, grub-pc, grub-efi-amd64-signed, shim-signed to package list (grub-install requires these, not just -bin variants)
- memtest hook: fix binary/boot/ not created before cp; handle both Debian (no extension) and upstream (x64.efi) naming
- bee-openbox-session: increase healthz wait from 30s to 120s

KVM console stability:
- runCmdJob: syscall.Setpriority(PRIO_PROCESS, pid, 10) on all stress subprocesses
- lightdm.service.d: Nice=-5 so X server preempts stress processes

Packages: add btop
