Outbound webhooks + Apprise bridge (bring your own notifier)

[Wikid82]

Why

Rather than building notification delivery for every possible channel, self-hosters already run notification hubs (Ntfy, Gotify, Pushover, Telegram, Discord, Matrix). Bridging to Apprise (or emitting plain outbound webhooks) gets all of them for the cost of one integration.

Proposed approach

• Emit outbound webhooks for household events (chore completed, overdue, reward redeemed) to a configurable URL
• Document wiring that webhook into a self-hosted Apprise API instance for multi-channel fanout
• Auth the webhook config UI using the token model from API foundation: long-lived access tokens #31

Depends on

#31 (API foundation).

Acceptance criteria

• A configured webhook URL receives a POST for at least chore-completed and chore-overdue events
• README documents pointing this at Apprise
