fix: make interactive project selection the default when no target provided

- Changed init command to trigger select_seren_database() when target is
  not provided AND --local flag is not set (default behavior)
- Updated error message to guide users when --local is used without --target
- Fixed README example: removed --local from interactive selection example
- Fixed README markdown lint warnings (blank line around list, broken link)
- Added postgresql-client to Dockerfile for pg_dump/pg_restore/psql tools
