Walkthrough

The changes remove two complete database initialization scripts for etcd and scylla dummy data, refactor the main initialization orchestrator to conditionally execute dummy scripts with fallback logic, and enhance MySQL verification with a two-step schema and user existence check.

Changes

Cohort / File(s)	Summary
Removed Dummy Initialization Scripts quick-start/db-init/scripts/init-dummy-etcd.sh, quick-start/db-init/scripts/init-dummy-scylla.sh	Deleted etcd bootstrap script that configured feature store keys, entities, and model configurations (-233 lines). Deleted ScyllaDB initialization script that created tables and inserted example data (-124 lines).
Conditional Dummy Script Execution quick-start/db-init/scripts/main-init.sh	Added conditional existence checks for dummy initialization scripts (etcd, scylla, mysql) before execution. Falls back to regular initialization paths for scylla and etcd if dummy scripts are unavailable. (+17 lines, -3 lines)
Enhanced Database Verification quick-start/db-init/scripts/verify-init.sh	Replaced simple admin user existence check with two-step MySQL verification: first validate users table schema exists, then check for admin user presence. Provides granular status messages for each verification step. (+9 lines, -5 lines)

In `@quick-start/db-init/scripts/verify-init.sh`:
- Around line 16-24: The final MySQL summary is hardcoded to assume the admin
exists; update verify-init.sh to compute a reusable status string after the
existing MySQL checks (use the ADMIN_COUNT result and the schema check) — e.g.,
set a variable like MYSQL_STATUS to either "admin user ✅" or "schema ready (no
admin user) ✅" based on ADMIN_COUNT and the table presence check, and then
reference that MYSQL_STATUS variable in the script's final summary output
instead of the fixed message; locate logic around the mysql check and the
ADMIN_COUNT variable to implement this change.
