Subject: [PATCH] fix: Pass bias-T setting to ADS-B and AIS dashboards

The bias-T checkbox on the main dashboard was not being passed to the
ADS-B and AIS tracking start requests. Added getBiasTEnabled() helper
to each dashboard that reads from shared localStorage, and updated all
start request bodies to include bias_t parameter.
