fix: pct create fails with malformed arguments (#423)

- Fix NS/MTU/MAC/VLAN/SD variables missing proper prefixes in base_settings()
  Variables were passed as raw values instead of formatted pct options
  (e.g., '192.168.1.1' instead of '-nameserver=192.168.1.1')

- Strip spaces from nameserver values to prevent 'too many arguments' error
  Multiple DNS servers must be comma-separated without spaces

- Auto-create database directory before Prisma initialization
  Fixes 'Cannot open database because directory does not exist' error
  for manual Git installations
