Replace build:sqlite with db:generate + build

Update build flow in ct/pangolin.sh and install/pangolin-install.sh to use `npm run db:generate` followed by `npm run build` instead of the old `npm run build:sqlite`. Also normalize a DB generation invocation by replacing `npm run db:sqlite:generate` with `npm run db:generate` in the installer. These changes consolidate DB generation and use the standard build step.
