feat(flightlab): sidebar, progress bars, skip speech, SimBridge telemetry & auth

- Add collapsible sidebar with phase stepper (jump between phases)
- Add SimBridge conditions panel in sidebar (live values, progress bars, targets)
- Add global progress bar (top edge, glowing) + phase-local TTS progress bar
- Add skip button to skip TTS speech while ATC is speaking
- Add skipSpeech() to audio composable (stops current Pizzicato sound)
- Wire up bridge data.post.ts with user auth (JWT) + example payload
- Add server-side telemetry store with pub/sub for Bridge→WS relay
- Extend WS handler with subscribe-telemetry message + userId tracking
- Extend sync composable with subscribeTelemetry() + onTelemetry() callback
- Add require-auth middleware to all flightlab pages
- Fix instructor station ECONNREFUSED via import.meta.client guard
- Add animations: phase transitions, button lists, fade-scale, check-pop, pulse
