0060_ssh_key: relocate ~/.ssh into encrypted data dir, generate non-interactively

Symlinks ~/.ssh to ${DECRYPTEDDATADIR}/ssh_keys (migrating any existing
content once) so the key lives in the gocryptfs-encrypted area instead
of the plain home directory. Also passes -N "" to ssh-keygen so key
generation no longer prompts for a passphrase.

+# 0060_ssh_key
+
+Provisions a per-user `~/.ssh/id_ed25519` key and escrows it in the FreeIPA
+KRA vault (`SSH_PRIV_KEY`), so the same key is reused across machines instead
+of generating a new one on every install.
+
+Run as the logged-in user via `client_software/user_run.sh` (needs the
+`DAVTOKEN_USER` environment prepared by `sync_client_software.sh`).
+
+Behavior:
+- `~/.ssh` is relocated to `${DECRYPTEDDATADIR}/ssh_keys` (the user's
+  gocryptfs-encrypted data dir) on first run: any existing content is moved
+  there once, then `~/.ssh` becomes a symlink to it. Subsequent runs detect
+  the symlink and skip this step.
+- If `~/.ssh/id_ed25519` already exists, it's left untouched.
+- Otherwise, tries `ipa vault-retrieve` for `SSH_PRIV_KEY`:
+  - found → key is fetched, permissions fixed to `0600`, public key derived.
+  - not found → a new vault is created, a new key pair is generated, and the
+    private key is archived to the vault.
+- Requires `IPAVAULTUSE=true` (KRA available); otherwise the script is a
+  no-op.
+
+Note: this only handles private-key escrow. Publishing the public key to the
+user's FreeIPA entry (`ipa user-mod --sshpubkey`) is not done by this script.
