Player Name requested to merge PlayerName/2009scape:oopsJarvald into master Aug 11, 2024

Depends on 2009scape/tools/rs09-constants-library!18 (merged), will fail to compile without it.

What has been done in this MR?

Removed leftover code from before Jarvald was ported to Kotlin. Fixes #1963 (closed).
Corrected a Jarvald NPC ID in constlib and made the server code use that instead of the raw number.

What should testers check?

Check that Jarvald's dialogue still opens normally. NPC IDs 2435-2438.

I have tested these changes thoroughly.
I used the relevant Zaros tool for any JSON edits where possible, and have attached screenshots of any changes.
