fix: live priority now interrupts long display durations (#196) (#298)

* fix: check live priority during display loops to interrupt long durations (#196)

_check_live_priority() was only called once per main loop iteration,
before entering the display duration loop. With dynamic duration enabled,
the loop could run for 60-120+ seconds without ever checking if a
favorite team's live game started — so the display stayed on leaderboard,
weather, etc. while the live game played.

Now both the high-FPS and normal FPS display loops check for live
priority every ~30 seconds (throttled to avoid overhead). When live
content is detected, the loop breaks immediately and switches to the
live game mode.

* fix: update rotation index when live priority interrupts display loop

The live priority break set current_display_mode but not
current_mode_index, so the post-loop rotation logic (which checks the
old active_mode) would overwrite the live mode on the next advance.

Now both loops also set current_mode_index to match the live mode,
mirroring the existing pattern at the top of the main loop (line 1385).

* fix: use timestamp throttle for live priority and skip post-loop rotation

Two issues fixed:

1. The modulo-based throttle (elapsed % 30.0 < display_interval) could
   miss the narrow 8ms window due to timing jitter. Replaced with an
   explicit timestamp check (_next_live_priority_check) that fires
   reliably every 30 seconds.

2. After breaking out of the display loop for live priority, the
   post-loop code (remaining-duration sleep and rotation advancement)
   would still run and overwrite the live mode. Now a continue skips
   directly to the next main loop iteration when current_display_mode
   was changed during the loop.
