fix: resolve traefik container dynamically in access-log cleanup (#4646)

Browse Source 
The nightly access-log-cleanup job hardcoded "dokploy-traefik" as the
container name when sending SIGUSR1. In Docker Swarm mode Traefik runs as
a service task named "dokploy-traefik.1.<task-id>", so `docker exec
dokploy-traefik` fails every night with "No such container". The log file
is rotated (inode changes) but Traefik never reopens it, leaving the
on-disk access.log frozen while real logs go to a deleted file handle.

Resolve the running container id dynamically with `docker ps --filter`,
matching the pattern already used elsewhere in the codebase, so it works
for both standalone and swarm deployments. Skip gracefully if no running
container is found.

Closes #4620
