mei: add DeepMEI 1000G subtrack on hg38

91,617 MEIs (68,282 Alu, 16,891 L1, 6,444 SVA) called by DeepMEI
on the 3,202 high-coverage 1000 Genomes samples. Same 1-bp anchor
convention and Okabe-Ito colors as meiHgsvc3. DeepMEI's symbolic
ALT carries no inserted sequence or insertion length, so the
bigBed schema is a subset of meiHgsvc3 (no svLen, callerCount,
validation flags, insertSeq). Also fixes the INS-svLen:carrierCount
label format note in meiHgsvc3.html. refs #37524
