[NO GBP] fixing a few issues with fishing and aquariums (#93964)

## About The Pull Request
Played around with fishing and aquariums the other day. While it has
come a long way, aquariums are still a pain in the ass in many ways and
there are still things that don't work as intended as well as some pet
peeves. This PR:
- removes code that didn't work to begin with (rotating the fish when
mounted on for fish trophy wallmounts)
- fixes the predator and necrophage traits triggering when the fish is
NOT hungry and on fishes that are bigger than the not-so-hungry fish,
rather than smaller.
- Add an examine line to fish tanks when full.
- Fixes evolution probability for self-reproducing fishes (purple
sludgefish should be 1 in 20, not 1 in 40)
- Fixes fish analyzers not being usable on equipped/held items.
- Nit with examine lines for fishing rods.
- Experiments handler devices won't announce when an experiment that
they cannot perform is completed. The big exception is the generic
experi-scanner. This means fish analyzers and operating computers will
no longer bug you about material scan experiments being completed.
- the ping sound from using lures should be a smidge louder and can be
heard from more than 1 tile away.

## Why It's Good For The Game
Issues with fishing and aquariums mainly, also a smidge of a code
improvement for experiment handlers.

## Changelog

🆑
fix: Fixed some fishes trying to eat other (bigger) fish while not
hungry. Also a nit with purple sludgefish being a bit too rare.
fix: Fixes fish analyzers not working with held or equipped fish or
aquariums (not in your backpack).
balance: Fish analyzers and operating computers no longer announce
completed experiments that they aren't compatible with.
balance: the ping sound from using fishing lures should be a smidge
louder and can be heard from more than 1 tile away.
qol: Examining fish tanks (the item) when they're almost full will warn
you about it.
