Rebalances watchers, base damage and status effect (#61223)

fixes #49999
Gives them a bit of base damage that's burn for carbons and brute for borgs so they can still self-repair
Gives them a slowdown on par with hardsuits that lasts just long enough to wear off if you dodge one more shot while under its effects
