Add server wipe detection

[HandyS11]

Summary

Adds server wipe detection to RustPlusBot. When the Rust server wipes, the bot now detects it on reconnect, announces it in the per-server #events channel, and purges all paired smart devices so no stale devices or dead alarm notifications survive the wipe.

Design spec: docs/superpowers/specs/2026-07-15-wipe-detection-design.md

What it does

• Detection — a new RustPlusBot.Features.Wipes project checks each reconnect transition (ConnectionStatusChangedEvent with IsConnected && !WasConnected), diffing live wipe time / map seed / map size against a baseline persisted on the RustServer row (new WipeDetection migration adds LastWipeTimeUtc, LastMapSeed, LastMapSize). A wipe fires when the wipe time advances beyond a 60s jitter tolerance, or the seed/size changes — so wipes that happen while the bot is offline are still caught on the next connect. The first observation after deploy backfills the baseline silently (no false announcement on upgrade).
• Announcement — a localized (en/fr) embed in #events: wiped-at relative timestamp, new map size + seed, and a re-pair reminder.
• @everyone ping — a new toggle button in the global #settings message (PingEveryoneOnWipe, default off).
• Device purge — Alarms, Switches, and StorageMonitors each subscribe to ServerWipedEvent and delete their DB rows first (the stale-notification guarantee — a late trigger for a dead entity finds no row and is dropped), then best-effort delete their Discord embeds. Idempotent; missing channel/message tolerated.
• The map needs no handling — RustMaps generation already keys on (size, seed), so the new seed regenerates it automatically.

Testing

• Full solution build clean (39 projects, -warnaserror).
• 1028 passed / 1 skipped across 18 test assemblies (36 new tests).
• No EF model drift; jb cleanupcode gate clean.

Notes

• Detection is event-driven (reacts to the existing connection-status event); ConnectionSupervisor is untouched.
• Spec deviation (documented in the plan): the PairedEntity purge was dropped — nothing in production writes that table.
• dotnet ef in this repo must use --startup-project src/RustPlusBot.Persistence (Host fails on a pre-existing packaging quirk).

Pull request overview

Adds a new “server wipe detection” feature to RustPlusBot that detects wipe signals on reconnect, announces the wipe in the per-server #events channel (optionally pinging @everyone), and purges paired smart-device state so stale entities/notifications don’t survive a wipe.

Changes:

• Introduces RustPlusBot.Features.Wipes (detector + hosted service + announcer + embed renderer + Discord poster) and the ServerWipedEvent abstraction event.
• Persists a per-server wipe baseline (LastWipeTimeUtc, LastMapSeed, LastMapSize) and adds a guild toggle (PingEveryoneOnWipe) with a new #settings UI button.
• Adds wipe purge handlers for Alarms, Switches, and StorageMonitors (DB rows removed first, then best-effort Discord message deletes), plus extensive test coverage.

Good catch — fixed in 249beb1. PostAsync now passes AllowedMentions.None for embed-only posts (content is null) and keeps AllowedMentions.All only when explicit ping content is present, so incidental mention-like text in the localized embed can never ping. Ping behavior on the @everyone path is unchanged.
