* feat(ssh): restore FIDO2 security key support (#2308)
Consolidate the restored feature and its review fixes before rebasing onto current main. Original PR head: 5d0a0c6c9a550364d3ec5c2331395cedfc9ea7ae.
* fix(ssh): verify and repair FIDO authentication with simulated hardware
Preserve complete OpenSSH SK signature payloads, classify combined PIN/presence prompts correctly, expand IdentityFile tokens, retain certificate selectors, and route shared-agent signing prompts to their originating window. Dismiss prompts when notification helpers exit. Add a software SK provider and opt-in real OpenSSH integration coverage for both algorithms, certificates, SFTP, forwarding, and concurrent windows.
* refactor(ui): refine security key forms and authentication motion
Use shared Select and Switch controls, concise localized copy and compact token-based dialogs. Add scoped enter/exit, field transition and presence animations with reduced-motion support. Preserve raw prompt details and visible PIN errors.
* fix(ssh): align security key prompts with hardware presence and verify Docker logins
* fix(ui): keep security key dialog above its remounted overlay
* fix: address Codex review on PR #2823
* feat(ssh): guide security key recovery and explicit authentication fallback
* test(ssh): exercise security key authentication on native Windows
* test(ssh): verify Windows fixture signatures and explicit fallback
* test(ssh): configure Windows OpenSSH toolchain and document coverage
