Install current 1Password from tarball on aarch64

[kvnloo]

Summary

Install current 1Password from the vendor tarball on aarch64.

Fixes #9576.

AUR 1password is x86_64-only. The deleted existence-only installer left Apple Silicon on 8.12.0. Fetch 1password-latest.tar.gz, skip only when the installed version already matches, and run vendor after-install.sh. Keep the pacman path on other architectures.

Testing

• install-1password-aarch64-test.sh FAIL on pinned quattro (tarball pin) / PASS on this SHA (9 ok)
• launch-1password-test.sh PASS

FYI, pkgs.omarchy.org/edge/aarch64 has carried a 1password package since
September 5 (omarchy-pkgs ca99c24), so the pacman path in
omarchy-install-service-1password already works on ARM. A fresh aarch64
install on edge sees 1password 8.12.34-35 with pacman -Si. The tarball
fallback may not be needed unless stable/rc matter before those trees publish.

Thanks @jdvmi00 — good catch.

Agreed: on edge aarch64, 1password is already in pacman (pkgs.omarchy.org/edge/aarch64 since ~Sep 5 / omarchy-pkgs ca99c24), so the existing omarchy-pkg-add path works there and a blanket tarball install is unnecessary.

Follow-up on this same PR: prefer pacman when 1password is resolvable on aarch64/arm64, and only use the official tarball + bundled after-install.sh when the package is missing (stable/rc lag). x86_64 path stays omarchy-pkg-add unchanged. No second PR.
