feat: Session Power Meter — 3D balance visualizer (#17 )

Add a glowing orb power meter to the Workshop scene that reflects the session balance in real time. - power-meter.js: new Three.js module — transparent outer shell, inner orb that scales 0→1 with fill fraction, lightning bolt overlay, point light and equator ring accent; DOM text label projected above the orb shows current sats. Color interpolates red→yellow→cyan. Pulses bright on 'fill' event, quick flicker on 'drain'. - session.js: imports meter helpers; tracks _sessionMax (initial deposit); calls setMeterVisible/setMeterBalance in _applySessionUI; triggers fill/drain pulses on payment and job deduction; exports openSessionPanel() for click-to-open wiring; clears meter on _clearSession. - websocket.js: handles session_balance_update WS event — updates fill level and fires pulse. - interaction.js: adds registerClickTarget(group, callback) — wired for both FPS pointer-lock and non-lock modes and short taps. - main.js: wires initPowerMeter/updatePowerMeter/disposePowerMeter into the build/animate/teardown cycle; registers meter as click target that opens the session panel.
