Fix remaining spam issues and phpcs merge conflict marker

Spam fixes:
- Add ZFS pool category to hash with subtypes (pool_state, pool_usage,
  pool_errors) so DEGRADED and usage-high on same pool get separate tickets
- Strip volatile percentages from LXC/ZFS usage titles ("usage high: 80.1%"
  → "usage high") and OSD counts from BlueStore slow-ops titles
  ("2 OSD(s) experiencing" → "OSD(s) experiencing") in hwmonDaemon.py

phpcs fix:
- Remove leftover merge conflict marker (<<<<<<< HEAD / >>>>>>>)
  in create_ticket_api.php which caused phpcs to fail on bitshift
  operator spacing

DB cleanup:
- Deleted 107 spam comments and 107 audit entries from tickets
  357934698 (ZFS pool), 673679581 (BlueStore), 925498317 (LXC storage)
