feat(participantTable): support seedlist with faction mode

[hjpalpha]

Summary

• support seedlist with faction mode
• rework display to be closer to table2
• move buttons on top of the table instead of in the title row
• kick some unused scss and js (checked per insource-search across wikis via fo's tool page)

How did you test this change?

Ideally we'd also have a golden test that shows the seed list, but OOS for this

Any perticular reason table2 can't be used?

Any perticular reason table2 can't be used?

for the seedlist only or for the partTable itself too?

for the seedlist we could change it to that probably
for the faction partTable probably too

for the non-faction partTable i doubt it since there is the width and flex handling in play

if you want i can test stuff out, but would prefer to do so in a stacked PR on #8165

[Rathoz]

You can make it on a stacked, that's fine

(only for faction mode and seedlist though, as for the "normal" one it is not usable without breaking the flex stuff)
