Tomas DvorakandDevin dbc87bf34c feat(services): sleep mode — scale-to-zero on idle, wake on traffic
Services gain sleep_enabled + sleep_idle_minutes. A 30s sweeper tracks
container NetworkIO deltas; a flat counter for the configured window
scales the service to zero (status=sleeping, workload containers removed).

While slept, a busybox wake container takes over the service's Traefik
host rule at priority 100: it serves a self-reloading "waking" page and
calls the unauthenticated idempotent GET/POST /api/v1/internal/wake/:id,
which reconciles the service back to running. Wake placeholders carry a
dedicated label (containr.wake-for) so runtime state never counts them;
the sweeper prunes them once the workload is up. The wake URL resolves
the API via its container name when containerized, else the edge
network's IPAM gateway — bare-metal installs need HOST=0.0.0.0 for the
callback.

Surfaces: PUT fields on services, POST /services/:id/sleep|wake,
CLI --sleep/--sleep-idle + services sleep|wake, 2 MCP tools (89 total),
OpenAPI paths/schema, and a Settings > Sleep card with toggle, idle
minutes, and manual sleep/wake plus a Sleeping badge.

Verified live: idle sweep scaled whoami-web to zero; the wake container
served the page on the edge network and its callback woke the service
(container recreated, status running, placeholder pruned).
