app.tls_cert_file and app.tls_key_file are incorrectly documented

[brennanjl]

The app.tls_cert_file and app.tls_key_file configs are not correctly documented, and should be renamed.

Previously, these configs allowed users to configure TLS for all of the RPCs provided by Kwil. However, when we moved the user service to JSON RPC, we removed the ability to configure TLS, since most users should just use nginx anyways. Now, the TLS configs only apply to the admin service and to comet BFT's RPC (which I am not sure why we ever had it do that in the first place).

Therefore, there are 3 changes we need to make:

• rename the configs to be app.admin_tls_cert_file and app.admin_tls_key_file
• remove the ability for these to be used to configure CometBFT's RPC
• update the documentation to make it clear these are only for admin

Doing this. Assuming you don't have this already done @brennanjl ?

I have not done this yet. Thanks.
