Renamed to CONSTANT DATABASE_VARS_FILE

- Moved MIG data build commands into a dedicated 02_build_data.yml task file.
- Added async execution (async: 3600, poll: 0) for non-blocking build.
- Introduced mig_wait_for_build variable to optionally wait for completion.
- Added debug message to inform how to disable waiting via build_data.wait_for=false for performance.
- Updated config to use nested build_data.enabled and build_data.wait_for structure.
- Adjusted variable lookups accordingly.

+Integration test: ensure no Jinja variables are used in handler *names*.
+
+Why this policy?
+- Handler identifiers should be stable strings. If you ever notify by handler
+  name (instead of a dedicated `listen:` key), a templated name can fail to
+  resolve or silently not match what `notify` referenced.
+- Even when `listen:` is used (recommended), variable-laden names make logs and
+  tooling brittle and can trigger undefined-variable errors at parse/run time.
+- Keeping handler names static improves reliability, debuggability, and
+  compatibility with analysis tools.
+
+Allowed:
+- You may still template other fields or use `listen:` for dynamic trigger
+  routing; just keep the handler’s `name` static text.
