The Bhima installation process currently requires manual execution of SQL scripts via shell scripts to build the database schema. This PR bundles SQL schema files with the application and automates their execution through the install.js controller, enabling zero-script deployment.

Implementation

Schema Setup Functions

• getSQLFiles() - Discovers and sorts .sql files from server/models/ by filename
• checkSchemaExists() - Queries information_schema to verify if critical tables exist (idempotency)
• processSQLWithDelimiters() - Parses SQL files containing DELIMITER commands for stored procedures/functions
• executeSQLFile() - Executes SQL statements sequentially, ignoring duplicate object errors (ER_TABLE_EXISTS_ERROR, ER_SP_ALREADY_EXISTS, etc.)
• setupDatabaseSchema() - Orchestrates complete schema setup (exported for external use)

Integration Point

Modified proceedInstall() to call setupDatabaseSchema() before creating enterprise/project/user:

exports.proceedInstall = async (req, res) => {
  const { enterprise, project, user } = req.body;

  const isInstalled = await basicInstallExist();
  if (isInstalled) {
    throw new BadRequest('The application is already installed');
  }

  // Setup database schema if it doesn't exist
  await setupDatabaseSchema();

  const location = await defaultEnterpriseLocation();
  await createEnterpriseProjectUser(enterprise, project, user, location.uuid);
  res.redirect('/');
};

Behavior

• First install: Executes all SQL files in order (01-schema.sql, 02-functions.sql, ..., 99-debug.sql)
• Existing schema: Detects presence via information_schema query and skips execution
• Partial failure: Idempotent error codes ignored, other errors logged and re-thrown
• DELIMITER handling: Correctly parses stored procedures/functions by tracking delimiter state per line

Backward Compatibility

Existing installation process unchanged. If schema was already built via build-database.sh, the existence check detects it and skips SQL execution.

Closes #8418.
