Fixes#13735
### What
This Pull Request introduces new database migrations to remove multiple redundant indexes across several core modules, including product, cart, order, customer, and inventory.
### Why
As detailed in issue #13735, a fresh Medusa installation produces numerous "Duplicate Index" warnings. These legacy indexes add unnecessary write overhead and provide no performance benefit. This PR cleans up the schema to resolve these warnings and improve database health.
### How
I have added one new, reversible migration file for each of the five affected modules:
- `@medusajs/product`
- `@medusajs/cart`
- `@medusajs/order`
- `@medusajs/customer`
- `@medusajs/inventory`
Each migration's `up()` method safely drops the older, redundant index, and its `down()` method re-creates it, ensuring the change is fully reversible and non-destructive.
### Testing
I have tested these migrations by following the local development workflow outlined in the `CONTRIBUTING.md` guide.
1. **Setup:**
* Cloned my forked Medusa repository locally .
* Created a separate, fresh test project using `npx create-medusa-app@latest my-medusa-store`.
* The test project's PostgreSQL database, which already contained the schema with the duplicate indexes.
2. **Linking Local Source Code:**
* In the test project's `package.json`, I modified all `@medusajs/*` dependencies and resolutions to point to the local packages in my forked repository (e.g., `"@medusajs/product": "file:../medusa/packages/modules/product"`).
* From the test project's directory, I ran `yarn install` to link the local, modified Medusa source code into its `node_modules`.
3. **Build & Migration:**
* Inside my forked Medusa repository, I ran `yarn build` to compile the new TypeScript migration files.
* From the root of the **test project**, I then executed the migration command: `npx medusa migration run`.
4. **Verification:**
* The command successfully identified and ran only the new migration files I had created.
* I also confirmed via direct SQL queries that the old, redundant indexes were correctly dropped from all affected tables (`product_collection`, `customer_group`, etc.).
## Summary
**What** — What changes are introduced in this PR?
Add a method in the Tax Module's servie to retrieve a provider by its ID.
**Why** — Why are these changes relevant or necessary?
The Tax Module Provider could be used for use cases other than calculating tax lines. For example, Avalara supports importing products to manage product-specific taxes. However, it's not possible right now to listen to the `product.created` event and create the product in Avalara with its provider. Instead, you'll have to create a separate module that also connects to Avalara and resolve it in the subsriber.
This also matches the pattern in the Analytics Module, which allows retrieving the underlying provider.
**How** — How have these changes been implemented?
Add a `getProvider` method to the Tax Module's service and its interface.
**Testing** — How have these changes been tested, or how can the reviewer test the feature?
Added integration test for the method.

## Additional Context
Add any additional context, related issues, or references that might help the reviewer understand this PR.
This pull request enhances the entity column generation logic in the admin views by adding support for including fields from additional GraphQL types, specifically for the `orders` entity. The changes allow more flexible and comprehensive column definitions by pulling in fields from related types (like `OrderDetail`) and updating the filtering and type resolution logic accordingly.
**This adding payment_status & fulfillment_status from OrderDetail in view configuration feature**
**Entity column generation enhancements:**
* Added the `ADDITIONAL_ENTITY_TYPES` mapping to specify extra GraphQL types whose fields should be included for certain entities (currently, `OrderDetail` for `orders`). ([packages/medusa/src/api/admin/views/[entity]/columns/helpers.tsR260-R263](diffhunk://#diff-ce197feb4e4d1273d9ee19126e284b65fdb4367f0871774a75add5c8cd749d02R260-R263))
* Updated the column generation process to collect fields from both the main entity type and any additional types, while properly filtering out arrays and excluded fields. ([packages/medusa/src/api/admin/views/[entity]/columns/helpers.tsR340-R345](diffhunk://#diff-ce197feb4e4d1273d9ee19126e284b65fdb4367f0871774a75add5c8cd749d02R340-R345), [packages/medusa/src/api/admin/views/[entity]/columns/helpers.tsR373-R414](diffhunk://#diff-ce197feb4e4d1273d9ee19126e284b65fdb4367f0871774a75add5c8cd749d02R373-R414))
* Changed field lookup logic to use a unified `entityFields` object and a new `additionalFieldDefinitions` map for extra fields, ensuring correct type info resolution for all columns. ([packages/medusa/src/api/admin/views/[entity]/columns/helpers.tsL344-R354](diffhunk://#diff-ce197feb4e4d1273d9ee19126e284b65fdb4367f0871774a75add5c8cd749d02L344-R354), [packages/medusa/src/api/admin/views/[entity]/columns/helpers.tsL411-R463](diffhunk://#diff-ce197feb4e4d1273d9ee19126e284b65fdb4367f0871774a75add5c8cd749d02L411-R463))
### What
Add a new `once` allocation strategy to promotions that limits application to a maximum number of items across the entire cart, rather than per line item.
### Why
Merchants want to create promotions that apply to a limited number of items across the entire cart. For example:
- "Get $10 off, applied to one item only"
- "20% off up to 2 items in your cart"
Current allocation strategies:
- `each`: Applies to each line item independently (respects `max_quantity` per item)
- `across`: Distributes proportionally across all items
Neither supports limiting total applications across the entire cart.
### How
Add `once` to the `ApplicationMethodAllocation` enum.
Behavior:
- Applies promotion to maximum `max_quantity` items across entire cart
- Always prioritizes lowest-priced eligible items first
- Distributes sequentially across items until quota exhausted
- Requires `max_quantity` field to be set
### Example Usage
**Scenario 1: Fixed discount**
```javascript
{
type: "fixed",
allocation: "once",
value: 10, // $10 off
max_quantity: 2 // Apply to 2 items max across cart
}
Cart:
- Item A: 3 units @ $100/unit
- Item B: 5 units @ $50/unit (lowest price)
Result: $20 discount on Item B (2 units × $10)
```
**Scenario 2: Distribution across items**
```javascript
{
type: "fixed",
allocation: "once",
value: 5,
max_quantity: 4
}
Cart:
- Item A: 2 units @ $50/unit
- Item B: 3 units @ $60/unit
Result:
- Item A: $10 discount (2 units × $5)
- Item B: $10 discount (2 units × $5, remaining quota)
```
**Scenario 3: Percentage discount - single item**
```javascript
{
type: "percentage",
allocation: "once",
value: 20, // 20% off
max_quantity: 3 // Apply to 3 items max
}
Cart:
- Item A: 5 units @ $100/unit
- Item B: 4 units @ $50/unit (lowest price)
Result: $30 discount on Item B (3 units × $50 × 20% = $30)
```
**Scenario 4: Percentage discount - distributed across items**
```javascript
{
type: "percentage",
allocation: "once",
value: 15, // 15% off
max_quantity: 5
}
Cart:
- Item A: 2 units @ $40/unit (lowest price)
- Item B: 4 units @ $80/unit
Result:
- Item A: $12 discount (2 units × $40 × 15% = $12)
- Item B: $36 discount (3 units × $80 × 15% = $36, remaining quota)
Total: $48 discount
```
**Scenario 5: Percentage with max_quantity = 1**
```javascript
{
type: "percentage",
allocation: "once",
value: 25, // 25% off
max_quantity: 1 // Only one item
}
Cart:
- Item A: 3 units @ $60/unit
- Item B: 2 units @ $30/unit (lowest price)
Result: $7.50 discount on Item B (1 unit × $30 × 25%)

When starting the Medusa application i see the following in the console:
```
update-order-tax-lines: "when" name should be defined. A random one will be assigned to it, which is not recommended for production.
({ input }) => {
return input.item_ids?.length > 0;
}

({ input }) => {
return input.shipping_method_ids?.length > 0;
}
