fix: keep Tailscale runtime mount fresh

[alihussainiF1]

What changed

Mount the Tailscale runtime directory in every Deploy Manager Compose configuration instead of bind-mounting only tailscaled.sock.

Why

When tailscaled restarts, it replaces the Unix socket inode. Long-running Deploy Manager containers kept the stale socket bind mount and all Tailscale SSH server checks and deployments failed until the containers were restarted. Mounting the containing directory lets the container resolve the replacement socket.

Validation

• docker compose config --quiet
• docker compose -f docker-compose.dev.yml config --quiet
• deploy image Compose configuration validation
• git diff --check
• Recovered production runner verified with matching host and container socket inode and a successful AllEyes deployment
