Fix Activepieces duplicate pieces and SmoothSchedule logo

- Remove piece_metadata inserts from SQL script (pieces are auto-discovered
  from filesystem as OFFICIAL, no need for duplicate CUSTOM entries)
- SQL now only sets pinnedPieces and cleans up any existing duplicates
- Fix SmoothSchedule logo URL to use production URL instead of lvh.me
- Fix deploy.sh to read correct POSTGRES_USER from env file
