[no gbp] few repairbot fixes and some beacon pathing improvements. (#88144)

## About The Pull Request
this fixes some few sentient repairbot-related issues that were reported
a few days ago. ive also given sentient repairbots a new simple UI to
manage their materials.

while I was at it, i also fixed bots continuously trying to path to
unreachable beacons, which can be quite costly since they're regularly
very far away.

## Why It's Good For The Game
