Switch to Bun runtime and update install scripts

Install Bun during setup and replace npm/npx calls with bun/bunx. Added Bun install (sets BUN_INSTALL, runs bun install script, and symlinks bun and bunx to /usr/local/bin) in install/blinko-install.sh. Updated ct/blinko.sh and install/blinko-install.sh to use `bun install`, `bunx prisma ...`, and `bun run build` instead of npm/npx commands for dependency install, Prisma generate/migrate, and build steps.
