Increase DrawDB RAM/disk and format homelable JSON

Raise default resources for DrawDB container: update ct/drawdb.sh to set var_ram from 2048 to 6144 and var_disk from 4 to 5 to allocate more memory and disk. Also adjust json/homelable.json formatting by expanding the categories array to multiple lines for readability; no functional metadata changes.
