Fixed plant analyzer crash when the plant graft gives reagent gene, rather than trait gene [NO GBP] (#89089)

## About The Pull Request

Didn't know that some plants have reagent traits defined for grafted
traits.

It didn't work because the trait_db contained only subtypes of
`/datum/plant_gene/trait`, but not `/datum/plant_gene/reagent`.

## Why It's Good For The Game

Fix

## Changelog

🆑
fix: Fixed plant analyzer UI crashing on plants that have a reagent gene
on their graft
fix: Plants with reagent traits in the graft now properly say the name
of the grafted reagent
