feat(panel): Beta sweep — multi-game coherence, honesty, UX fixes

Multi-game rebrand (no more Rust-only leftovers): game-neutral setup wizard +
deploy/store defaults; player-id labels driven by game profile (Steam ID only
for Rust); blueprint wipe type + verify-plugins gated to uMod games; oxide
command examples + Rust-only plugin pages (AutoDoors/FurnaceSplitter/BetterChat)
guarded behind mods==='umod' with empty-states for other games.

Honesty: webstore checkout shows coming-soon (backend now 503s); 'integrated
webstore' marketed as coming-soon; Discord references neutralized to
community/webhook; migration FAQ marked in-development; analytics dev phase
labels removed; Network pricing tier set to Custom/Contact (was a confusing
duplicate of Operator); docs/PRICING.md rewritten to match live subscriptions.

UX/bugs: fixed ServerView oxide-status operator-precedence bug; dead 'Deploy
server' button wired; non-functional topbar search removed; alert()/confirm()
replaced with toasts across schedules/alerts/migration/public store+server;
analytics chart arrays null-guarded; production console.logs gated to DEV.

Frontend build (vue-tsc + vite) green.
