[MIRROR] Allows Signers to send COMSIG_MOB_SAY [MDB IGNORE] (#24982) (#…

* Allows Signers to send COMSIG_MOB_SAY (#79677)

## About The Pull Request
By removing a conditional statement which prevented signers from sending
a `COMSIG_MOB_SAY` signal (for some reason), this PR fixes a few things
in one go:

- Sign language once again prints a notice that the signer raises or
lowers their eyebrows for exclamations and questions respectively.
- Tonal indicators (sign/typing icons that depict eyebrows raising or
lowering) are also working again.
- RuneChat is now punctuated the same as the chat box for Signers.

This PR is now atomic thanks to @ MrMelbert.
