[Data - 2745] Fix update metadata

[Zhimin-arya]

The cause is when add new dataset:

1. The cache_id hasn't been passed down to the create_cache_file plugin, so the cache is written into {database_code}.db
   Fix: derive cache_id after new dataset created and pass it when trigger create_cache_file plugin
2. After new dataset created, the trex didn't create the cache_id.db accordingly.
   Fix: set createDbFileIfMissing: true
3. When update the metadata, each dataset check against its own cache_id catalog

Pull request overview

This PR aims to fix dataset “update metadata” / cache-related behavior by ensuring cache DB files can be attached/created when missing and by propagating a cache_id through dataset creation and cache creation flows.

Changes:

• Trex startup and DBM attach route now call ensureAttached(..., { createDbFileIfMissing: true }) when attaching cache DBs.
• Dataset function now includes a derived cache_id in the create_datamodel flow options payload.
• Cache DB file creation flow now uses cache_id (when provided) to choose the DuckDB target database name and DuckDB file path; OMOP CDM flow passes cacheId through to the cache creation flow.
