Winston Waves Reward Notifier

When the vanilla Winston Waves gives you wave rewards, there's no explicit message. With this mod, a clickable letter will pop up to address the issue in the original mod where rewards were airdropped but "you had no idea where they went."

Features:
A letter appears in the letter interface whenever wave rewards are granted.

If the rewards include physical items: clicking the letter's jump button teleports you to the freshly generated drop pod location.
If the rewards are purely effect‑based (healing, research, favor, etc., with no physical object): the letter has no jump button.

The letter body includes the reward name, description, and detailed contents (item/pawn counts, special effects, etc.).

Compatible with Winston Waves Reward Scaler.

Configurable in the mod settings: toggle notifications on/off, switch between detailed or condensed content display, and choose the letter color type.
