fix(player): create AudioContext before resuming so first click plays

handlePlay called resumeAudio() before connectAudio(), but at that
point the module-level ctx in lib/audio.ts is still null — resumeAudio
returned Promise.resolve() and the gesture window was wasted on a
no-op. connectAudio() then created a fresh AudioContext in suspended
state, audio routed through its destination stayed silent, and the
listener had to click play a second time to get sound.

Reorder to: connectAudio (creates the context), resumeAudio (resumes
inside the same gesture), then el.play().
