os-apply: proxmox-grub joins the boot-chain lane (pve step refused R6 nightly on demo-felhom)

proxmox-grub 2.12-9+pmx4 depends on grub-efi-amd64 of the same version. HOST_SLOW_RE
anchors `grub` at the start of a name, so proxmox-grub landed in the ring-0 pve plan,
the simulation pulled grub-efi-amd64, and the whole pve step was refused R6 every
night since 2026-11-05. Same class as the 2026-10-09 proxmox-secure-boot-support fix.

Test test_ring0_pending_pve_leaves_proxmox_grub_out: red before the fix, green after.

-`50eeccc`, CI job 2552 green. `<state dir>/store-grant-seen.json` remembers which tiers held their grant; a first grant logs INFO and reports healthy; a doubt (no file path, an unreadable or corrupt file) keeps the ERROR. Tests `TestR1302_*` (`cmd/felhom-agent/storegrant_test.go`), seen failing before the code existed and on four mutants. Not seen live: it needs a release and the operator's vouch. A box updated to it records its tiers at the first healthy probe, so a loss in the one probe before that reads as a first grant.
