Fix description template strings not rendering (missing f-string prefix)

All multi-line ASCII art blocks in _generate_ticket_description were
regular strings, not f-strings — so {hostname}, {'━' * box_width},
{cluster_health}, etc. were sent as literal template text instead of
rendered values. Added f prefix to all affected triple-quoted strings:
banner, executive_summary, DRIVE SPECIFICATIONS, DRIVE TIMELINE,
SMART STATUS, PARTITION, CEPH CLUSTER STATUS, CPU STATUS,
NETWORK STATUS, CONTAINER STORAGE.
