This PR is a duplication of #18754 (which targets the `symfony-8`
branch). It reuses that PR's commits to bring the broadened Doctrine
support into `2.3`.

### What it does

Widens the supported Doctrine stack, **opt-in via `||`, no minimum is
bumped**:

  - `doctrine/doctrine-bundle` `^2.13 || ^3.0`
  - `doctrine/dbal` `^3.9 || ^4.0`
  - `doctrine/persistence` `^3.3 || ^4.0`
  - `doctrine/data-fixtures` `^1.7 || ^2.2` (dev)

Plus the compatibility work the newer stack requires:

- DBAL 3.x/4.x compatibility layers (platform detection,
`getSchemaManager()` → `createSchemaManager()`,
    `SqlitePlatform`/`SQLitePlatform`, `QueryBuilder::select()`);
- a custom `ObjectType` registered as `object` (the built-in `object`
type was removed in DBAL 4),
covering the only two `type="object"` mappings:
`PaymentSecurityToken.details` and `PaymentRequest.payload`;
- config updates: removed `auto_generate_proxy_classes` (gone in
DoctrineBundle 3), PSR-6 cache pools,
and forced `SEQUENCE` identity generation on PostgreSQL to keep the
schema backward compatible;
  - CI matrix entries to test both DoctrineBundle 2 and 3.

## Summary by CodeRabbit

* **New Features**
  * Added support for DoctrineBundle 3 and DBAL 4.
  * Added a custom DBAL “object” type to keep payment data compatible.
* **Documentation**
* Added Sylius 2.3 upgrade notes, including Doctrine cache pool
migration and PostgreSQL identity/sequence behavior.
* **Bug Fixes**
* Updated Doctrine ORM cache configuration to use Symfony cache pools
(production and test setups).
* Fixed timestamp handling to consistently store mutable `DateTime`
values where required.

+2. Configuration changes related to the broadened Doctrine support (see the *Dependencies* section). 
+   These only matter once you opt into **DoctrineBundle 3** / **DBAL 4**:
+
+   - The `auto_generate_proxy_classes: "%kernel.debug%"` option was removed from Sylius' Doctrine configuration 
+     (it no longer exists in DoctrineBundle 3, and since PHP 8.4 Doctrine uses native lazy objects). If you are still 
+     on DoctrineBundle 2 and rely on this behavior, set it explicitly in your own application configuration.
+
+   - The ORM metadata/query/result cache configuration was switched from wrapped `Doctrine\Common\Cache` services 
+     to **PSR-6 cache pools** (`type: pool`). This change lives in the application configuration (`config/packages/{prod,test}/doctrine.yaml`), 
+     which is **not** updated automatically on existing installations, update those files in your project accordingly:
+
+     ```diff
+     doctrine:
+         orm:
+             entity_managers:
+                 default:
+                     metadata_cache_driver:
+     -                    type: service
+     -                    id: doctrine.system_cache_provider
+     +                    type: pool
+     +                    pool: doctrine.system_cache_pool
+     ```
+
+     As part of this switch, the `doctrine.result_cache_provider` and `doctrine.system_cache_provider` services 
+     (defined in Sylius' application configuration, wrapping the PSR-6 pools via `Doctrine\Common\Cache\Psr6\DoctrineProvider`) 
+     were **removed**. If you referenced them by id, use the cache pools directly (`doctrine.system_cache_pool`, 
+     `doctrine.result_cache_pool`) with `type: pool` as shown above.
+
+   - On **PostgreSQL**, Sylius now forces the `SEQUENCE` identity generation strategy 
+     (`identity_generation_preferences` for `PostgreSQLPlatform`) to keep the database schema backward compatible 
+     with existing installations.
+
 ## Dependencies
 
 1. The `behat/transliterator` package has been **deprecated** and will be removed in Sylius 3.0.
@@ -68,6 +100,14 @@
 
    If your application depends on these packages directly, require them explicitly in your `composer.json`.
 
+4. The supported Doctrine version ranges have been **broadened** to allow the newer stack
+   (`doctrine/doctrine-bundle` `^2.13 || ^3.0`, `doctrine/dbal` `^3.9 || ^4.0`,
+   `doctrine/persistence` `^3.3 || ^4.0`, `doctrine/data-fixtures` `^1.7 || ^2.2`).
+
+   DBAL 4 removes the built-in `object` and `array` column types. Since Sylius maps two fields 
+   as `type="object"` (`PaymentSecurityToken.details` and `PaymentRequest.payload`), it registers
+   a custom `Sylius\Bundle\PaymentBundle\Doctrine\DBAL\Type\ObjectType` to keep them working.
+
 ## Deprecations
 
 1. Passing a `Sylius\Component\Core\Calculator\ProductVariantPricesCalculatorInterface` directly to the following catalog-facing classes is deprecated since Sylius 2.3.
