Storyteller Narration Filters (#21767)

This PR adds a feature requested of me by @Fyniiy , adding optional
Filters to the Narrate panel that allow Storytellers to narrate only to
people that meet a set condition. The conditions themselves were
specifically requested to be "Psi Narrates" and "Synth Narrates", with
optional variations on Synth narrates that include people with cranial
implants. While I was touching these files, I've also fixed the improper
message sanitization bug with admin messages in general.

Here's a breakdown of the filter options.

1. **Skrell-like Psi-sensitives**: Anyone with a Psi-sensitivity score
of "At least 1". This will include Skrell, anyone with a Psi-receiver,
and people with the High Psi-sensitivity trait. It will exclude people
who are blocked from receiving telepathy for any reason, such as having
a mindshield, mindblanker, or having the psi-suppression power active.
Skrell with the Low Psi-sensitivity trait are counted as "Human-like
Psi-sensitives", and so won't be caught by this filter.
2. **Human-like Psi-sensitives**: Anyone who isn't blocked from
receiving telepathy, and also has a Psi-sensitivity score of "At least
0". This will basically catch "Most people who aren't a Vaurca,
Synthetic, or Diona". It will ignore Humanoids with the Low
Psi-sensitivity trait.
3. **Silicons**: Basically all of the possible robots/IPCs.
4. **Silicons + Implants**: It's fairly common practice during Hivebot
related events for Storytellers to also include characters with brain
implants. This filter automates that by including said brain implant
owners in the "Are you a synthetic?" check.
5. **Hivenet**: Pretty simple, people with the Vaurca language. This
would be Vaurca, plus anyone with the hivenet implants.
