Draft: Lunar Series: Dream

What has been done in this MR?

• Rewrote Dream spell

What should testers check?

• The Dream spell will restore a player's Hitpoints at 3 times the normal rate (or one hitpoint every 20 seconds). It is a Lunar Magicks spell. This effect ends with any activity other than chat, including trade, movement, logout, attacking, being attacked, and eating.

• I have tested these changes thoroughly.

• I used the relevant Thanos/Zaros tool for any JSON edits where possible, and have attached screenshots of any changes.
