fix(launcher): add sync pause toggle and reduce default polling intervals

Browse Source 
The SWR pattern always fires a background API call on cache hits, so the
15s session interval created a continuous API stream even when data was
fresh. Increased all defaults: session 15s->60s, location/device 30s->60s,
presentation/presenter 45-60s->120s.

Added sync_paused guard to all six refresh functions and a Pause/Resume
toggle in the Sync Timers config section (visible without edit mode) so
testing and troubleshooting don't require a full reload.
