Strip volatile values from ticket titles (usage %, OSD counts)

- LXC/ZFS storage usage percentages: "usage high: 80.1%" → "usage high"
- LXC "high storage usage: 80.1% on /mnt" → "high storage usage on /mnt"
- Ceph BlueStore OSD counts: "2 OSD(s) experiencing slow" →
  "OSD(s) experiencing slow" (count fluctuates every run)

These changing values embedded in titles were triggering a "Title updated"
comment on every hourly run even though nothing meaningfully changed.
Values are fully retained in the ticket description.
