raidboss: UCOB timeline phase sync fixes

[valarnin]

Depends on #153, will rebase once that's merged.

This cleans up and fixes the syncs for the HP %-based pushes in UCOB phase one, by instead detecting the Neurolink puddle drops.

Had to adjust the timeline a bit to allow the sync to work due to the original timeline not having proper phase definitions.

For reference, there are a few objects that get spawned in UCOB that I've seen up to my current prog point:

On zone init / after wipe:

ID	Description	Count	X	Y (height, not reversed with Z)	Z
001E8536	Unknown	1	0	0	18
001EA1A1	Unknown	3	0	0.0171	0
001E850B	Unknown	1	0	0	-20
001EA1A1	Unknown	3	0	0	0

During pull:

ID	Description
000006EB	Unknown. Spawns ~8s into pull, and at the same time the 3rd Neurolink spawns
001E8910	Twister puddles
001E88FF	Neurolink puddles
001E88FE	Liquid Hell puddles
001E91D4	Wings of Salvation doom cleanse puddle
001E91C1	Looks like this is the Hypernova puddle? Timing is slightly off so not 100% sure, could be caused by animation delay
001EA7E5	Giant fireball for the phase transition to Bahamut Prime
001E9663	"pepperoni" towers in QMT

I have left a TODO in the timeline to change the CombatantMemory syncs to use a potential new SpawnObject OP log line depending on how that side of the equation works out.

Rebase to main, and add another sync fix for Nael => Bahamut phase transition

LGTM, with one suggestion and a question about detecting the phase 3 jump based on Nael going untargetable. I probably won't be back in UCOB until after the next tier, so if this looks good to you in terms of the phase detection, good w/me.

Edit: Sorry, forgot to add: I think SpawnObject would be a good add, but I'll take a look at the stuff you posted on the OP issue and leave any comments there.
