[Tech Debt] Deprecate name and displayName fields

[FI00ds]

Description

With i18n being used for all displayed text, we no longer need to use the name and displayName properties from the Character and Lightcone types/classes

Remove them from the class and type, and replace any existing uses to instead reference the character/lightcone by their id

[FI00ds]

also track down any possible uses of, and then remove, the readable formattign for stats, sets, etc... anything intended to be readable should be going through i18n
