chore: configurable database migration in concurrency (#14004)

> [!NOTE]
> Adds a configurable concurrency for link migrations (CLI/commands), forces concurrency=1 when pgstream is detected, and ignores duplicate link-table inserts.
> 
> - **CLI**
>   - Add `--concurrency` option to `db:migrate` and `db:sync-links`.
> - **Medusa commands**
>   - `migrate` and `sync-links` accept `concurrency`; set `DB_MIGRATION_CONCURRENCY` and force `1` when `pgstream` schema exists via new `isPgstreamEnabled`.
> - **Link Modules (migrations)**
>   - Execute plan actions with `executeWithConcurrency` using `DB_MIGRATION_CONCURRENCY`.
>   - Make link-table tracking inserts idempotent with `ON CONFLICT DO NOTHING` (including bulk/upsert and per-create).
