Timer Front-End view

[tedyoung]

• [x] Set up WebSocket via HTMX and receive the HTML of the timer display every second
• [x] Make the timer page accessible to Participants/Spectators
• [X] HTML Template: JavaScript to play sound when timer reaches zero using ~~htmx-trigger~~ a kludge of wsAfterMessage and inspecting the HTML directly for what gets returned when the timer is finished. Might want to add a separate element that is dedicated to that purpose, generalizable for a "ws-trigger" element that could invoke any other function.
• [x] Reset timer button
• [X] Play sound when Paused/Resumed
• [ ] Add Cache headers for sound effects
• [ ] Add "Rotate Participants" button (i.e., skip current turn)
• [ ] Replace horn.wav with custom edited sound
• [ ] Allow choices for "finished" sound
• [ ] Add an indicator for when a full rotation is completed.
