POINT 3 Replay Pro V6

Fixes:
- Replay returns to LIVE automatically after the replay duration.
- Adds BACK TO LIVE NOW button in Director for instant return.
- During replay, normal scoreboard is hidden.
- A broadcast-style REPLAY animation bar appears instead of the scoreboard.
- Overlay uses 250ms no-cache sync and local auto-hide to avoid OBS delay.

Install:
1) Extract/overwrite into project root.
2) Open install_replay_pro_patch.php once in browser.
3) Hard refresh Director and OBS Browser Source cache.

Optional:
Set replay duration in overlay/director page before this JS loads:
<script>window.POINT3_REPLAY_DURATION = 8;</script>
