Discover NocoDB table IDs dynamically instead of hardcoding them

Table IDs are now fetched at runtime via the NocoDB meta API using
VITE_NOCODB_BASE_ID, so the same code works against any NocoDB instance
(local or Cloudron). Also adds a migration script for moving data between
instances with correct FK remapping.
