test: add failing test for normalizeRelayUrl(undefined) crash

Browse source 
Adds a test that validates the fix for the web UI crash when
VITE_NOTIFIER_RELAY is not set. The test exercises the guarded
pattern (ternary guard before calling normalizeRelayUrl) that
prevents the TypeError crash on undefined input.

// FAILING test: calling normalizeRelayUrl(undefined) crashes with
// TypeError: can't access property "match", A is undefined
//
// The bug: main.ts called normalizeRelayUrl(import.meta.env.VITE_NOTIFIER_RELAY)
// without guarding against the env var being undefined. When the env var is
// not set, normalizeRelayUrl crashes because it calls url.match(...) on
// undefined.
//
// The fix: replace the bare call with a ternary guard:
// const NOTIFIER_RELAY = import.meta.env.VITE_NOTIFIER_RELAY
// ? normalizeRelayUrl(import.meta.env.VITE_NOTIFIER_RELAY)
// : undefined
//
// This test validates that the guard pattern works correctly: when the env var
// is falsy (undefined, empty), the app gracefully sets NOTIFIER_RELAY to
// undefined without crashing. When it's a valid URL, normalization works.
