Make a dead lock client diagnosable and recoverable (#6630)

* Persist the Omarchy shell log across sessions

Quickshell only logs to its instance runtime dir on tmpfs, so when the
shell dies the idle/lock event trail is gone after a reboot (#6628).
Launch the shell through omarchy-launch-shell, which pipes stdout/stderr
into the journal under the omarchy-shell tag — bounded, timestamped, and
persistent — and surface that log in omarchy-debug-idle.

* Recover a locked session whose lock client died

When the shell dies while the session is locked, Hyprland's failsafe
keeps the session locked with no lock client left, and
omarchy-restart-shell refused to run in exactly that state, leaving
reboot as the only way back in (#6628). Gate the refusal on the lock
service actually holding (or acquiring) the lock rather than on the
session's LOCK state — a dead shell and a crash-handler relaunch that
holds no lock both fail that check — then restart the shell, re-acquire
the session lock, and wait for it to report secure, the same
secure-poll omarchy-system-sleep-lock uses, so the user can
authenticate out of the failsafe. Enable Hyprland's
allow_session_lock_restore so the compositor accepts the replacement
lock client.
