Summary of changes since D257.

Combat Backend performance regression fixes:
- Creating Fire Delays have been optimized. (Fire delays created within the duration of the sync may generate raw errors instead of proper messages, this will fix for new fire delays).
- Internal combat hooks have been optimized.
- Fixed performance issue when combat generates discord notifications.

Scanner filter changes:
- Added more cockpit scanner filters, and added the ability to save the filter so it applies across pageloads.

- Fixed issue with Discord Notifications. (Fixes cause of outage on D269).
- Fixed an issue where AI bots causing crash; certain public rules pages are now cached more aggressively. (Fixes cause of outage on D273).
- Fix issue where factions were not unassigned as commander of assets after dissolution.
- Fixed issue with journal events ordering, when they were sent at the same time.
- Reworked stim and antidote actions so they only occupy the medical slot if the performing entity has one. (Previously also occupied the working slot)
